A strong 150-gallon fuel tank should match both the fuel and the installation: the RDS tank suits diesel transfer, while the truck-specific options target particular makes, sides, and fill layouts. This roundup compares 10 tanks, including aluminum and steel transfer models and replacement tanks for Peterbilt, Kenworth, Volvo, and Mack trucks. The key distinction is not capacity—all are presented as 150-gallon options—but whether a tank is a transportable transfer tank or a vehicle-fit replacement.
Check dimensions, rear- versus other fill details, driver- or passenger-side orientation, and vehicle-year compatibility before choosing. Some listings provide precise fitment and construction details; others give only a model name and dimensions, so verify those gaps against your truck before ordering.
The RDS 150 Gallon Diesel Transfer Tank leads for buyers who need a clearly specified transfer tank: it holds 150 gallons, is aluminum, and measures 48 x 28 x 28 inches. It is explicitly for diesel only, so it is not the right choice for gasoline or as a truck-specific replacement. For a truck installation, choose a replacement matched to the make, model, side, fill position, and dimensions instead; the Mytee Products option lists a broad range of Peterbilt fitments and a 26 x 72-inch size.

Detailed Reviews: Best 150 Gallon Fuel Tank

#1 · Best Overall
1. RDS Diesel Transfer Tank
- Capacity: 150 gallons
- Material: Aluminum
- Compatible with Vehicle Type: Truck
Best for: Diesel pickup transfer tank.
Why it ranks #1: A clearly specified 150-gallon aluminum transfer tank measuring 48 x 28 x 28 inches; the listing explicitly limits it to diesel fuel.
A 150-gallon capacity in a 48-by-28-by-28-inch rectangular aluminum tank gives truck owners a substantial diesel-transfer option in a clearly specified footprint. Its diesel-only fuel restriction makes the intended liquid explicit, helping buyers distinguish it from tanks listed for broader fuel or vehicle-replacement applications.
The aluminum construction and 158-pound listed weight identify the tank’s material and handling consideration before installation; its 48-inch length, 28-inch width, and 28-inch height give buyers concrete dimensions to compare with available truck space. A 150-gallon capacity supports carrying a sizable diesel supply, while the diesel-only restriction narrows its use to that fuel. The listing calls it a transfer tank, so it suits buyers seeking transport rather than a model-specific replacement tank.
- 150-gallon capacity
- Aluminum construction
- Specified 48 x 28 x 28-inch dimensions
- Clearly restricted to diesel fuel
- Diesel fuel only; it is not listed for gasoline or other liquids.
Skip it if you need a Peterbilt-specific replacement; the BestFit PBDS150 lists Peterbilt fitments and a 26 x 72-inch profile.
Choose this RDS tank if your truck-based workflow calls for transporting diesel and its rectangular 48 x 28 x 28-inch footprint suits the available space. Its stated diesel-only use is an important boundary for buyers handling other fuels.

View on AmazonWhy it ranks #2: This 150-gallon rectangular steel transfer tank includes a mounting kit, lockable cap and coupler, and dual reinforced 2-inch bungs.
A lockable cap and coupler paired with dual flush-mounted, reinforced 2-inch bungs give this 150-gallon steel transfer tank practical pump-mounting and access details. Its listed overfill restriction allows automatic pump shut-off, making it a fit for buyers who want transfer-tank features specified together.
The included mounting kit supports installation, while dual reinforced bungs provide pump-mounting locations that are flush mounted. A lockable cap and coupler allow venting, combining access control with the listed venting function. The overfill restriction permits automatic shut-off at the pump, a useful part of the filling workflow. Steel construction and a 171-pound listed weight are relevant handling considerations; the description identifies transport and storage of non-flammable liquids as its intended use.
- Lockable cap and coupler

3. Mytee Peterbilt Rear Fill Tank
Best for: Broad Peterbilt truck fitment.
Why it ranks #3: The 26 x 72-inch, 150-gallon rear-fill left-hand tank lists fitment across numerous Peterbilt models and an 18-month warranty.
A listed fitment range extending from Peterbilt 330 through 387 models makes this 150-gallon, 26-by-72-inch rear-fill tank a candidate for several truck applications. Its left-hand placement and named replacement OEM reference give buyers concrete details to compare against a current installation.
The 26-by-72-inch dimensions and 150-gallon capacity describe the tank’s size and storage volume, while the rear-fill, left-hand configuration identifies its installation orientation. The listed fitments include Peterbilt 330, 335, 352, 359, 362, 375, 377, 378, 379, 386, and 387 ranges, supporting a more targeted compatibility check.

4. BESTfit Peterbilt Early Tank
- Capacity: 150 gallons
- Material: Aluminum
- Compatible with Vehicle Type: Truck
Best for: Early-style Peterbilt replacement.
Why it ranks #4: This aluminum 150-gallon, 26 x 72-inch rear-fill tank identifies early-style Peterbilt driver-side fitments and provides a two-year warranty.
A 26-by-72-inch profile and driver-side rear-fill layout identify this 150-gallon BestFit tank for buyers replacing a specific Peterbilt installation. Its listed fitments span several Peterbilt generations, so the model and year details help narrow whether this aluminum replacement matches the truck.
The aluminum construction and 150-gallon capacity provide the core replacement specifications, while the 26-inch height and 72-inch length help compare the tank with the available mounting space. Rear fill and driver-side placement matter to the truck’s fueling and installation arrangement. The listed applications include Peterbilt 330, 335, 352, and 359 model-year ranges; the three replacement OE numbers offer additional identification points when matching a current tank.

5. BESTfit Peterbilt Late Tank
- Capacity: 150 gallons
- Material: Aluminum

Best for: Late-style Peterbilt replacement.
Why it ranks #5: The 150-gallon aluminum driver-side tank measures 26 x 72 inches and lists later Peterbilt applications, including models 337 and 348.
A driver-side, 26-by-72-inch rear-fill configuration and listed Peterbilt applications make this BESTfit tank a targeted 150-gallon replacement option. The named late-style positioning and aluminum construction help distinguish it from other Peterbilt tank configurations in the roundup.
The 150-gallon stated capacity and aluminum material establish the tank’s core specifications, while the 26-inch diameter and 72-inch length help compare available space. Driver-side placement and rear fill clarify orientation and fueling access. The supplied fitment description names Peterbilt 335, 337, 348, 365 SBA, 365 SFA, and 367 applications; those vehicle details are more useful for replacement selection than capacity alone.

#6 · Kenworth Fit Option
6. BESTfit Kenworth Rear Fill Tank
- Capacity: 150 gallons
- Material: Aluminum
- Compatible with Vehicle Type: Truck
Best for: Kenworth front-manifold replacement.
Why it ranks #6: A 150-gallon aluminum driver-side rear-fill tank for Kenworth, with a 24.5-inch diameter, 74-inch length, and front manifold detail.
A driver-side front manifold positioned 20 inches from the front weld distinguishes this 150-gallon BESTfit tank for a Kenworth replacement search. The 24.5-inch diameter and 74-inch length add useful size references, while its rear-fill configuration clarifies the fueling arrangement.
The aluminum tank’s 150-gallon capacity suits buyers seeking that stated volume, and its 24.5-inch diameter by 74-inch length provides a concrete space comparison. Driver-side placement and rear fill establish the orientation, while the specified front manifold location—20 inches from the front weld to its center—offers a precise reference for matching the existing layout. The listing describes it as a factory-style replacement made to OE specification.
- 150-gallon capacity
- Aluminum construction
- 24.5-inch diameter and 74-inch length

7. BESTfit Volvo Mack Tank
- Capacity: 150 gallons
- Compatible with Vehicle Type: Truck
Best for: Volvo VNL and Mack tank.
Why it ranks #7: This 150-gallon driver-side rear-fill tank is listed for Volvo VNL and Mack, with 11-gauge aluminum and dimensions of 26 x 69.75 inches.
A 150-gallon capacity in a 26-by-69.75-inch rear-fill driver-side tank identifies this BESTfit option for Volvo VNL and Mack truck applications. Its 11-gauge aluminum and welded seams provide additional construction details for buyers comparing replacement tank specifications.
The 11-gauge aluminum construction and welded seams are specified alongside the stated aim of preventing leakage, giving buyers concrete construction information to weigh. Its 26-inch diameter and 69.75-inch length help assess space, while rear fill and driver-side placement define the arrangement. A 150-gallon capacity sets the listed storage volume, and the stated Volvo VNL and Mack application narrows the vehicle match rather than implying universal compatibility.
- 150-gallon capacity
- 11-gauge aluminum

A 26-by-72-inch profile and rear-fill right-hand designation make the World American WA911-150-26PRO a specifically identified tank configuration. Its title states 150-gallon capacity, giving buyers useful volume, orientation, and size information for narrowing a replacement search.
The stated 150-gallon capacity provides the tank’s volume, while the 26-by-72-inch dimensions help compare its footprint with a current installation. Rear fill and right-hand placement specify the arrangement, which matters when matching a truck’s existing tank position and fueling access. The listing identifies the World American model as WA911-150-26PRO, but supplies no vehicle make or model fitments, so the named configuration is the available basis for evaluating fit.

The listed 150-gallon capacity establishes the intended volume, while the 24-by-74-inch dimensions provide a space reference for replacement planning. Rear fill and left-hand placement narrow the configuration and can guide comparison with an existing tank’s access and position. The supplied model identifier is WA911-150-24DR.

10. Generic Kenworth Fuel Tank
- Capacity: 150 gallons
- Material: Aluminum
- Compatible with Vehicle Type: Truck
Best for: Kenworth aluminum replacement.
Why it ranks #10: It is described as an aluminum 150-gallon rear-fill tank for Kenworth, but the listing supplies no dimensions or specific fitment details.
A 150-gallon capacity and Kenworth-specific title make this aluminum tank a basic candidate for buyers seeking a rear-fill replacement. The listing also identifies truck compatibility and aluminum material, but provides no dimensions or detailed model-year applications to refine the match.
The stated 150-gallon capacity establishes the intended volume, while aluminum construction identifies the material buyers are considering for a truck tank. Its title specifies rear fill and Kenworth, giving a broad vehicle and fueling-layout starting point for replacement research. However, the supplied specifications do not provide dimensions, side placement, or model-year fitments, so those details cannot be used here to narrow the installation or confirm a particular truck application.
- 150-gallon capacity
- Aluminum material
- Kenworth named in the title
- Rear-fill configuration named in the title
- No tank dimensions or specific Kenworth model-year fitments are supplied.
Skip it if you require stated dimensions and Peterbilt fitments; BestFit PBDS150 supplies a 26 x 72-inch profile and named Peterbilt applications.
Consider this generic tank when the Kenworth and rear-fill description aligns with your search and the listed 150-gallon aluminum specification meets your needs. The sparse fitment details make it a limited choice for precise replacement matching.

Listed on Amazon as: For Kenworth Aluminum Generic 150 Gallon Fuel Tank Rear Fill
View on AmazonTransfer tanks and replacement tanks serve different jobs
A transfer tank is for transporting or storing fuel; a replacement tank is meant to fit a specific truck installation. The RDS model is expressly a diesel-only transfer tank, with a rectangular 48 x 28 x 28-inch body. The Better Built model is also a transfer tank and specifies a steel body, mounting kit, lockable cap and coupler, and reinforced pump bungs.
By contrast, several aluminum listings identify a truck make, side, and fill orientation—for example, the Mytee Products tank is a rear-fill, left-hand Peterbilt replacement. Treating these categories as interchangeable can lead to a tank that holds the right volume but cannot be mounted or connected as intended.
Before ordering, establish whether you need a transportable tank or a replacement, and verify the fuel type, mounting arrangement, and connection requirements. The RDS listing says diesel only; do not assume another fuel is compatible without confirmation from the manufacturer.
A tank’s nominal volume does not confirm truck fit
Matching a 150-gallon capacity alone does not establish that a replacement tank will fit. These listings include different dimensions and orientations: the BESTfit Kenworth tank is 24.5 inches in diameter and 74 inches long, while the BESTfit Volvo and Mack tank is 26 inches in diameter and 69.75 inches long. The Peterbilt options include 26 x 72-inch tanks, but one targets early-style applications and another lists late-style applications.
Side and fill details matter too: a right-hand tank is not a substitute for a left-hand tank simply because the capacity matches. Listings also vary in how much fitment information they provide; the Generic Kenworth entry, for example, gives no dimensions.
Compare the truck’s existing tank, mounting location, fill position, manifold placement, and vehicle-specific fitment details with the listing. If a critical measurement or fitment fact is missing, confirm it before purchase rather than relying on capacity or a broad make name.
How to Choose a 150-Gallon Fuel Tank
Tank type and fuel compatibility
First decide whether you need a transfer tank or a truck-specific replacement, then verify the permitted fuel. The RDS model is a 150-gallon aluminum transfer tank and explicitly says diesel only. Better Built lists a 150-gallon rectangular steel transfer tank with a mounting kit, lockable cap and coupler, and reinforced bungs.
The remaining detailed models are primarily vehicle replacement tanks for particular truck applications. A buyer transporting diesel can start with the RDS; someone needing steel transfer construction can consider Better Built.
For a truck replacement, prioritize the make, model, side, fill layout, and dimensions rather than choosing a transfer tank by volume alone. Do not infer gasoline compatibility from a listing that does not state it.
Dimensions and truck fitment
Look for dimensions and vehicle-specific fitment that match your installation, not just a 150-gallon label. Listed sizes range from the RDS transfer tank at 48 x 28 x 28 inches to truck tanks such as the 24.5 x 74-inch BESTfit Kenworth model and 26 x 69.75-inch BESTfit Volvo and Mack model. Peterbilt choices include 26 x 72-inch tanks, but early- and late-style applications differ.
The Mytee Products tank lists numerous Peterbilt models, while the Generic Kenworth listing gives no dimensions. Buyers with a confirmed Peterbilt application may favour the detailed fitment lists; buyers replacing a tank with a different size should verify measurements and mounting clearances first.
Treat unspecified dimensions as a reason to confirm compatibility, not as evidence of universal fit.
Side, fill position, and manifold layout
Check the tank’s side and connection layout against the truck before ordering. Listings distinguish driver-side or left-hand from right-hand tanks, and several specify rear fill; the BESTfit Kenworth option also describes a front manifold and gives a 20-inch measurement from the front weld to the manifold center. Mytee Products identifies a left-hand rear-fill Peterbilt tank, while World American offers separate right-hand 26 x 72-inch and left-hand 24 x 74-inch listings.
These are not interchangeable details: the wrong side, fill position, or manifold location can prevent a replacement from matching the installation. Buyers replacing an existing tank should compare these details directly with it.
If a listing does not state the layout clearly, seek confirmation before relying on its capacity or truck make alone.
Which 150-Gallon Fuel Tank Should You Choose?
For diesel transport in a clearly specified aluminum tank, choose the RDS Diesel Transfer Tank: it is 150 gallons, measures 48 x 28 x 28 inches, and is explicitly diesel-only. If you want a steel transfer tank with a mounting kit, lockable cap and coupler, and reinforced pump bungs, consider the Better Built Steel Transfer Tank. For a Peterbilt replacement, the Mytee Peterbilt Rear Fill Tank has the broadest listed Peterbilt fitment; match its left-hand rear-fill layout and 26 x 72-inch dimensions to your truck.
The BESTfit Peterbilt Early Tank and BESTfit Peterbilt Late Tank target different applications, so check the listed model years and dimensions. Kenworth buyers can compare the BESTfit Kenworth Rear Fill Tank with the more sparsely specified Generic Kenworth Fuel Tank, verifying fit details before ordering.

Frequently Asked Questions
How can I confirm a replacement tank will fit my truck and mounting setup?
Match the tank to your truck’s make, model, application, side, and fill position, then compare its listed dimensions with your available mounting space. Check the exact product fitment details before ordering; Peterbilt early- and late-style tanks target different applications, and a listed fitment range alone may not confirm your truck’s setup.
Can a 150-gallon diesel transfer tank be used for gasoline?
Do not assume a diesel transfer tank is suitable for gasoline. The RDS tank is explicitly specified for diesel only, so it is not the right choice for gasoline. Check the intended fuel and product documentation for any tank you are considering, and choose one specifically approved for your fuel.
What installation parts, pump, and fittings should I check before ordering?
Check what the listing includes and what your installation requires before ordering. Confirm whether a mounting kit, pump, cap, coupler, and compatible fittings are included or need to be sourced separately. The Better Built option lists a mounting kit, lockable cap and coupler, and reinforced pump bungs; verify compatibility with your setup.
How do I choose between a transfer tank and a truck replacement tank?
Choose based on the job: a transfer tank is intended for transporting fuel, while a replacement tank must match your truck’s fitment and mounting layout. The RDS option is a clearly specified, diesel-only transfer tank, not a truck-specific replacement. For a replacement, compare vehicle fitment, side, fill position, and dimensions.
What should Peterbilt and Kenworth buyers compare among these options?
Peterbilt buyers should match the listed application and dimensions: the Mytee tank lists a broad range of Peterbilt fitments, while the BESTfit early- and late-style tanks serve different applications. Kenworth buyers can compare the BESTfit rear-fill tank with the generic option, but should verify fit details because the generic listing is more sparsely specified.
Final Words
For diesel transport in a clearly specified aluminum tank, the RDS option provides 150-gallon capacity and listed dimensions of 48 x 28 x 28 inches, but it is diesel-only and not a truck-specific replacement. For truck fitment, match make, model, side, fill position, and dimensions. Peterbilt buyers can compare the broad Mytee fitment with the early- and late-style BESTfit options; Kenworth buyers should verify details closely.
