Best Fuel Filter For Ecodiesel: Compare 10 Options

#1 · Best Overall

1. Doc's Diesel Filter Kit

• Outer Material: Metal or Plastic
• Compatible with Vehicle Type: Jeep Wrangler / Gladiator 3.0L EcoDiesel, Ram…

Best for: Tested-efficiency kit seekers.

Why it ranks #1: Lists 2020–2023 Ram 1500 and Jeep EcoDiesel fitment and reports third-party-tested 99 percent efficiency down to 25 microns.

Third-party testing is the defining detail: Doc’s Diesel reports 99 percent efficiency down to 25 microns for this filter kit. The listing covers 2020–2023 Ram 1500, Wrangler, and Gladiator 3.0L EcoDiesel applications, making the stated filtration figure and newer-vehicle coverage its most useful differentiators.

The reported 99 percent efficiency down to 25 microns gives buyers a specific filtration benchmark, and the listing says it comes from independent testing. Its fitment spans Jeep Wrangler and Gladiator 3.0L EcoDiesel models from 2020–2023 and Ram 1500 3.0L EcoDiesel models from 2020–2023. A fitment card is provided for checking the exact year and configuration, which matters because the broad model range does not itself resolve every vehicle variant.

Skip it if you want an included oil filter and housing cap assembly; ZONFANT ZON-OF-68507598AA+68436631AA lists both items.

This kit suits EcoDiesel owners who value a stated independent filtration result and fall within its listed 2020–2023 applications. Use the fitment card to check the exact vehicle configuration, since model name and year alone may not settle fit.

#2 · Genuine Separator

2. Mopar 68436631AA Kit

• Weight: 0.26 kg
• Outer Material: Plastic
• Compatible with Vehicle Type: Ram Trucks

Best for: Ram separator kit shoppers.

Why it ranks #2: This genuine Mopar fuel/water separator kit is listed for Ram Trucks and includes a 12-month, 10,000-mile limited warranty.

The fuel-and-water separator designation makes the Mopar 68436631AA kit the clearest choice here for buyers seeking that specific filter type for a Ram truck. Its listing identifies a filter kit and Ram Trucks compatibility, giving owners a useful starting point, though it does not supply EcoDiesel model-year details.

The named fuel/water separator function distinguishes this item from listings that identify only a fuel filter, helping buyers focus on the component type they are seeking. Mopar branding and stated Ram Trucks compatibility provide make-level context, while the 68436631AA model number gives a reference for matching the part. The listing calls it a filter kit, but does not detail its contents or specify compatible Ram model years, engine size, or installation steps.

Skip it if you require explicit EcoDiesel year coverage; CARBBIA 081703 lists Ram 1500 EcoDiesel applications for 2020–2023.

Choose this when Mopar branding and a Ram-compatible fuel/water separator kit match your search. Its listing leaves year and engine fitment unspecified, so it is not sufficient by itself to establish compatibility with a particular EcoDiesel.

#3 · Oil Filter Bundle

3. CARBBIA Filter Set

• Compatible with Vehicle Type: Truck

Best for: Multi-filter EcoDiesel service set.

Why it ranks #3: Covers listed Ram and Jeep EcoDiesel applications in the newer model range and bundles a 68436631AA fuel filter with an oil filter.

CARBBIA packages a fuel/water separator filter and an oil filter, addressing two listed service items together. Its applications cover 2020–2023 Ram 1500 EcoDiesel and 2021–2023 Jeep Gladiator EcoDiesel, with Wrangler coverage also named in the listing, making the combined set and broad vehicle range its main draws.

The package lists one 68436631AA fuel filter and one 68507598AA oil filter, which can streamline sourcing when both are needed. CARBBIA identifies paper as the material and cites Ahlstrom media, ISO validation, and IATF quality control in its additional facts. The application text names Ram 1500 and Jeep Gladiator EcoDiesel years, while Wrangler is also identified; check the full listing for the exact Wrangler year range before purchase.

Skip it if you need a clear Wrangler year range in the supplied fitment; Doc's Diesel DGF430+D11880 states 2020–2023 Wrangler coverage.

This set suits owners looking to source fuel and oil filters together for a listed Ram 1500 or Gladiator EcoDiesel. Wrangler buyers should check the complete application details, because the supplied fitment excerpt does not give its full year range.

#4

4. ZONFANT Filter Set

• Weight: 0.46 kg
• Outer Material: Acrylonitrile Butadiene Styrene
• Compatible with Vehicle Type: Jeep Wrangler

Best for: Newer EcoDiesel service pair.

Why it ranks #4: Includes a fuel filter element and oil filter housing cap assembly, with listed Ram 1500, Wrangler, and Gladiator EcoDiesel fitment.

A fuel filter element paired with an oil filter housing cap assembly gives the ZONFANT set two service components in one package. Its stated applications cover 2020–2022 Ram 1500 and Jeep Wrangler EcoDiesel vehicles, plus 2021–2023 Gladiator EcoDiesel models, making its multi-vehicle fitment the key buying distinction.

The package includes one fuel filter element and one oil filter housing cap assembly, so a buyer seeking both listed items can source them together rather than separately. Its stated Ram 1500 coverage runs 2020–2023 in the additional description, while Wrangler coverage is 2020–2022 and Gladiator coverage is 2021–2023; check the exact vehicle application against those ranges. The ABS material is specified, but the listing provides no filtration efficiency figure.

Skip it if you need a published filtration figure; Doc's Diesel DGF430+D11880 reports third-party-tested 99 percent efficiency down to 25 microns.

This set fits buyers servicing a listed later-model EcoDiesel who also need the included oil-filter housing cap assembly. Its vehicle ranges differ by model, so verify your exact year and configuration before relying on the application listing.

#5 · Earlier Ram Fit

5. K&N PF-4500 Filter

• Weight: 4.96 oz
• Outer Material: Glass
• Compatible with Vehicle Type: Truck

Best for: K&N media-focused Ram owners.

Why it ranks #5: Specifically lists 2014–2017 Ram 1500 3.0L EcoDiesel compatibility and includes a fuel filter and O-ring.

Pleated cellulose-glass media is the K&N PF-4500’s defining feature, paired with stated compatibility for 2014–2017 Ram 1500 3.0L EcoDiesel engines. The listing presents it as a direct replacement that supports clean fuel delivery, giving buyers a named media type and a defined older-Ram application.

K&N says its pleated cellulose-glass media provides fuel-system protection, while its direct-replacement claim helps identify the filter’s intended role in place of an OEM 3.0 EcoDiesel filter. The stated fitment is limited to 2014–2017 Ram 1500 3.0L EcoDiesel models, so buyers of later years or other makes should not infer compatibility. An O-ring is listed among the included components, useful context when planning the replacement.

Skip it if you own a 2018–2019 Ram 1500 EcoDiesel; iFJF 68235275AA lists Ram 1500 3.0L V6 fitment through 2019.

This is a focused option for 2014–2017 Ram 1500 3.0L EcoDiesel owners who want a named media type and an included O-ring. Its stated model-year coverage does not extend to newer Ram applications.

#6

6. Mopar 68235275AA Filter

• Weight: 2.88 oz
• Outer Material: Plastic
• Compatible with Vehicle Type: Passenger Car, Truck

Best for: Mopar replacement buyers.

Why it ranks #6: A Mopar replacement listing identifies the superseding number 68235275AB and passenger car or truck compatibility, but gives no EcoDiesel year range.

The Mopar identity and documented supersession to part 68235275AB are this filter’s clearest practical distinction: buyers looking for the updated Mopar-numbered item can identify the current reference rather than relying only on the older title number. Its listing describes a fuel filter for passenger cars and trucks, but supplies no EcoDiesel-specific fitment details.

The listing names 68235275AB as the model and manufacturer part number, while the title retains 68235275AA; that supersession helps buyers track the updated reference when researching a Mopar replacement. Its stated passenger-car and truck compatibility is broad, not a specific EcoDiesel application, so it does not establish fit for a particular Ram or Jeep. The 2.88-ounce weight and plastic outer material give basic handling context, but no filtration rating or installation components are specified.

Skip it if you need verified EcoDiesel year-and-model coverage; Doc's Diesel DGF430+D11880 lists specific 2020–2023 applications.

This suits a buyer researching a Mopar-numbered replacement who can establish fit from separate vehicle-specific information. The listing’s broad passenger-car and truck category alone is not enough to confirm an EcoDiesel application.

#7

7. iFJF 68235275AA Filter

• Weight: 0.13 kg
• Outer Material: Plastic
• Compatible with Vehicle Type: Truck

Best for: Older Ram 1500 filter replacement.

Why it ranks #7: Lists Ram 1500 3.0L EcoDiesel fitment for 2014–2019 and a 10-micron filtration claim, with a 90-day warranty.

A stated 10-micron filtration specification sets the iFJF element apart for owners of 2014–2019 Ram 1500 3.0L V6 EcoDiesels. The listing also connects a dirty filter with starting, idle, and acceleration problems, framing replacement as routine fuel-system maintenance rather than a broader service kit.

The 10-micron rating gives a concrete filtration specification, and the listing says the element supports fuel flow while filtering harmful particles and water. Its compatibility is narrowly stated for Ram 1500 3.0L V6 EcoDiesel models from 2014–2019, helping older-truck owners assess relevance. This is a fuel filter element, not a multi-filter package; the listed included component is the fuel filter, so buyers seeking oil-service parts need a separate source.

Skip it if you need a listed Jeep EcoDiesel application; K&N PF-4500 covers 2014–2017 Ram 1500, while this iFJF listing is Ram-only.

This element is a fitment-specific option for owners of 2014–2019 Ram 1500 3.0L V6 EcoDiesels who want a stated 10-micron figure. Its listed application does not extend to Jeep models or newer Ram years.

#8 · Wrench Included

8. WONEHI Filter and Wrench

• Outer Material: Plastic
• Compatible with Vehicle Type: Light Truck

Best for: Filter-and-wrench DIY kit.

Why it ranks #8: Lists 2014–2019 3.0L diesel fitment and includes a 61150 four-tab housing wrench, filter element, and O-ring.

The included 61150 housing hex wrench is this WONEHI kit’s most practical distinction: it supplies a tool alongside the fuel filter and O-ring for the listed service. WONEHI names 2014–2019 Ram, Dodge, Jeep, and Chrysler 1500 3.0L diesel applications, giving the kit broad stated make coverage.

The kit combines a 68235275AA fuel filter, one O-ring, and a 61150 wrench, so buyers receive the listed parts and a dedicated housing tool together. The wrench’s four protrusions are described as engaging the housing, supporting a more purpose-specific approach than a general wrench. Fitment is stated for 2014–2019 1500 3.0L diesel engines across four makes; the listing advises checking filter size and model before ordering.

Skip it if you need a published filtration rating; iFJF lists a 10-micron specification for its 2014–2019 Ram 1500 EcoDiesel element.

This kit suits DIY owners whose vehicle matches the listed 2014–2019 1500 3.0L diesel applications and who want the housing wrench included. Confirm the filter size and model, as WONEHI specifically advises checking both.

Listed on Amazon as: 68235275AA fuel filter with 61150 filter housing hex wrench for 2014-2019 Ram, Dodge, Jeep, and Chrysler 1500 3.0L V6 diesel engines.

#9

9. UMONIE Filter and Wrench

• Outer Material: Plastic
• Compatible with Vehicle Type: Light Truck

Best for: Housing-wrench replacement kit.

Why it ranks #9: Includes a 61150 housing wrench and lists several replacement numbers, but its supplied fitment details do not specify model years.

UMONIE pairs a 68235275AA fuel filter with a 61150 four-tab housing wrench, making the included service tool its clearest practical feature. The listing describes evenly engaging the filter-cap slots and distributing torque, and identifies use on 3.0L EcoDiesel engines operating at up to 29,000 PSI.

The four-tab 61150 wrench is described as engaging the filter-cap slots evenly and distributing torque, which gives buyers a dedicated tool for the housing rather than relying on a strap wrench or vice grips. The filter lists several replacement numbers, including 68235275AA and PF-4500, and the listing cites operation on 3.0L EcoDiesel engines up to 29,000 PSI. It does not provide model-year fitment, so exact vehicle application remains a key boundary.

Skip it if you need stated model-year fitment; WONEHI 68235275AA lists 2014–2019 1500 3.0L diesel applications.

This kit fits a buyer who wants a dedicated four-tab housing wrench with a replacement filter and can verify vehicle fit separately. The listing’s pressure figure does not establish compatibility with a specific model year or make.

#10

10. Doc's Diesel Grand Cherokee Set

• Weight: 0.54 kg
• Compatible with Vehicle Type: Truck

Best for: Grand Cherokee filter-set buyers.

Why it ranks #10: The title specifies Grand Cherokee 3.0L EcoDiesel for 2014–2019, but its feature text also mentions Nissan Titan XD, making fitment less clear.

Doc’s Diesel identifies this set specifically for 2014–2019 Grand Cherokee 3.0L EcoDiesel applications, pairing fuel and oil filters for that service interval. Its premium three-layer fuel-filter media and OEM-form, fit, and function claims are the central reasons to consider it for an older Grand Cherokee.

The fuel and oil filter set combines two service items, which can simplify sourcing when both are due for replacement. Doc’s says the fuel filter uses premium three-layer media and that its filters are specified to meet or exceed original-filter quality and performance; those claims give buyers more detail than a bare replacement listing. The title states 2014–2019 Grand Cherokee 3.0L EcoDiesel fitment, while the listing does not offer a filtration micron figure.

Skip it if you need an explicitly listed Ram 1500 application; Doc's Diesel DGF430+D11880 covers Ram 1500 EcoDiesel models from 2020–2023.

This is a relevant set for Grand Cherokee owners within the stated 2014–2019 3.0L EcoDiesel range who want fuel and oil filters together. Its title does not establish fit for newer Grand Cherokees or other vehicles.
