Best 7 3 High Pressure Fuel Pump for Mazda 2.3L Models

#1 · Best Overall

1. TRQ High Pressure Fuel Pump

• Compatible with Vehicle Type: Car
• Weight: 2.2 lb

Best for: DIY Mazda repair planners.

Why it ranks #1: Lists Mazda 3, Mazda 6, and CX-7 2.3L applications, several matching reference numbers, and a limited lifetime warranty.

TRQ pairs this pump with a large catalog of DIY replacement videos, giving home repair planners a specific installation-learning resource alongside the part itself. Its reference-number list and named Mazda applications also support fitment cross-checking, while its product description cites upgraded plunger, sleeve, and valve designs for reduced wear.

TRQ lists several reference numbers, including HM10104 and the L3K9-13-35Z variants, which can help buyers compare the pump with the part being replaced. Its fitment details cover specified 2.3L Mazda 3, Mazda 6, and CX-7 applications, while the DIY video catalog provides a separate resource for preparing a repair. TRQ also describes improved plunger, sleeve, and valve designs intended to reduce wear. Check the exact application and reference before purchase.

Skip it if you need installation guidance included without consulting a separate video source; HAWK BROTHER L3K91335ZA directs installers to its manual or a professional.

TRQ suits Mazda owners planning a DIY replacement who can use its videos and reference list to prepare and verify the part. Match the exact engine, year, and reference number; the video resource does not replace fitment checking.

#2 · Broad Mazda Fitment

2. HAWK BROTHER L3K91335ZA Pump

• Compatible with Vehicle Type: Car

Best for: Mazda multi-model replacement.

Why it ranks #2: Names Mazda 3, Mazda 6, and CX-7 applications and lists L3K91335ZA, L3K91335ZB, and L3K91335ZC reference numbers.

Coverage across three Mazda lines is the defining strength of HAWK BROTHER’s L3K91335ZA pump: it serves listed Mazda 3, Mazda 6, and CX-7 model years. That range can simplify the search for owners replacing a pump in one of those applications, while its stated no-modification installation makes the replacement process more direct.

The listing names compatible years for Mazda 3 (2007–2013), Mazda 6 (2006–2007), and CX-7 (2007–2012), giving buyers a clear starting point for checking their application. It also cites several OE/OEM references, including L3K91335ZA, L3K91335ZB, and L3K91335ZC, which helps cross-check the replacement part. HAWK BROTHER says installation requires no modification or adjustment, though it directs installers to follow the manual or professional guidance for correct use.

Skip it if you need a pump for a vehicle outside the listed Mazda years; DrCax HM10104 is another listed option to assess for its own fitment.

Mazda owners seeking a metal replacement pump for the listed 2006–2013 applications can consider this option, especially when its cross-referenced OE numbers match. Check the exact model year and follow the supplied installation guidance.

#3 · 12-Month Warranty

3. DriveFix 2.3L Fuel Pump

• Compatible with Vehicle Type: Car
• Weight: 958 g

Best for: 2.3L Mazda owners.

Why it ranks #3: Specifies 2.3L fitment for Mazda 3, Mazda 6, and CX-7, plus a 12-month manufacturer warranty.

DriveFix gives a specifically 2.3L Mazda application range, naming the CX-7, Mazda 3, and Mazda 6 with their model years. That engine-and-year detail gives owners a focused fitment screen, while the included-component description identifies the item as one high-pressure fuel pump rather than a multi-part kit.

The listing covers Mazda CX-7 2.3L models from 2007–2012, Mazda 3 2.3L from 2007–2013, and Mazda 6 2.3L from 2006–2007. Those engine and year limits help narrow a replacement search to the stated applications. DriveFix identifies the included component as one pump and gives L3K9-13-35ZC as the model and part reference, enabling another check against the existing component. The supplied details do not describe installation steps or drive mode.

Skip it if you need stated installation instructions or a specified drive mode; HAWK BROTHER L3K91335ZA describes installation guidance.

This is a focused candidate for owners of the listed 2.3L Mazda applications who can match both engine and model year. Treat fitment as the key boundary, since the supplied details do not explain installation or operation.

4. WOWAUTO L3K9-13-35ZC Pump

• Compatible with Vehicle Type: Car
• Weight: 0.89 kg

Best for: Mechanical Mazda replacement.

Why it ranks #4: Lists Mazda 3, Mazda 6, and CX-7 fitment with 2.3L applications and identifies L3K9-13-35ZC as the OE part number.

WOWAUTO explicitly labels this L3K9-13-35ZC pump as mechanical, a useful distinction for Mazda owners comparing replacement operating modes. Its fitment details name 2.3L Mazda 3, Mazda 6, and CX-7 applications across specific years, pairing the drive-mode information with a concrete vehicle check.

The listing covers Mazda CX-7 2.3L from 2007–2012, Mazda 6 2.3L from 2006–2007, and Mazda 3 2.3L from 2007–2013. Matching both engine size and year narrows the fitment decision. WOWAUTO identifies the pump as mechanical and gives L3K9-13-35ZC as the OE part number, so buyers can compare drive mode and reference number with their replacement needs. It also describes the item as an OE replacement with easy installation, stable characteristics, and high reliability.

Skip it if you need a pump for an application beyond the listed 2.3L Mazda years; DriveFix L3K9-13-35ZC lists the same stated Mazda engine ranges.

This fits buyers seeking a mechanically operated replacement for the listed 2.3L Mazda applications and able to match the OE reference. Check both engine size and model year; the listing does not extend beyond those stated ranges.

5. GAZTUO L3K91335ZC Pump

• Compatible with Vehicle Type: Car

Best for: Mazda fitment cross-checkers.

Why it ranks #5: Names Mazda 3 and CX-7 applications and includes the L3K91335ZC reference, though the listed application years are narrower.

GAZTUO lists Mazda 3 and CX-7 fitment alongside the L3K91335ZC reference, giving buyers two concrete details to compare with their vehicle and removed pump. Its automatic operation is also specified, while the listing explicitly urges shoppers to verify year, make, model, and OE number before selecting this replacement.

The stated coverage includes 2009–2013 Mazda 3 and 2009–2012 Mazda CX-7, so buyers should use those years as a first screen rather than assume broader compatibility from the title. Checking the OE number against the replaced part adds another specific fitment check, as the listing recommends. GAZTUO describes the pump as automatic and says it is intended to support engine performance, responsiveness, and efficient combustion, but the supplied material does not give further installation details.

Skip it if you need listed Mazda 6 coverage; HAWK BROTHER L3K91335ZA lists Mazda 6 for 2006–2007.

This suits Mazda 3 and CX-7 owners whose years and replacement OE number match the listing and who value an explicit fitment-check reminder. Its supplied application details do not cover Mazda 6, so keep the search vehicle-specific.

#6

6. DrCax L3K91335ZC Pump

• Compatible with Vehicle Type: Car

Best for: Stainless-steel pump seekers.

Why it ranks #6: Identifies HM10104 and stainless steel construction, but its listing asks buyers to verify vehicle fitment rather than naming Mazda applications.

DrCax specifies a stainless-steel body and gerotor style, giving buyers two concrete construction and design details to weigh when choosing a replacement. The listing also calls the pump an automatic, ready-to-use direct replacement and emphasizes checking vehicle fit by year, make, model, and OE number before ordering.

Stainless-steel body material is the clearest construction detail, while the gerotor style identifies the product’s stated design. Together these specifics help buyers compare it with a removed pump or another replacement listing, though they do not establish vehicle compatibility by themselves. DrCax describes the unit as ready to use and a direct replacement, and recommends checking fitment through vehicle details and the replaced part’s OE number. It also says the pump is factory tested and made under strict quality control standards.

Skip it if you need a stated Mazda year range; WOWAUTO L3K9-13-35ZC lists Mazda 3, 6, and CX-7 applications.

DrCax is worth considering when stainless-steel construction and a gerotor designation matter to your comparison. Its direct-replacement description is not a substitute for vehicle-specific confirmation, so check the OE reference and application before installation.

#7

7. RYBVWNLB L3K9-13-35ZC Pump

• Weight: 50 g

Best for: Versatile pump-use shoppers.

Why it ranks #7: Lists a Mazda 3–7 application range for 2007–2013 and the L3K9-13-35ZC reference, but provides limited specific vehicle detail.

The RYBVWNLB listing describes both electric and mechanical drive approaches, making drive method its most distinctive point for buyers comparing pump applications. It also names a metal construction and the L3K9-13-35ZC interchange reference, though its broad claims about other machinery call for careful vehicle-specific checking before purchase.

The product information presents electric drive as offering fast response and high control accuracy, while mechanical drive is described as simple and reliable. That distinction can help a buyer understand the listed drive options, but the supplied facts do not identify which method this specific pump uses. Its metal construction and L3K9-13-35ZC reference provide concrete details for comparison; the stated fit is for 3–7, 2007–2013, so verify the vehicle application before relying on that broad wording.

Skip it if you require a clearly specified drive mode; WOWAUTO L3K9-13-35ZC explicitly lists mechanical operation.

Consider this only if its broad stated vehicle range and interchange reference match your application and you can resolve the drive-method ambiguity. The electric-versus-mechanical discussion is useful context, not confirmation of this unit’s mode.

#8 · Stated Pressure Range

8. NZMSMS L3K9-13-35ZC Pump

• Weight: 50 g

Best for: Turbo pressure specification seekers.

Why it ranks #8: States a 1,500–2,200 PSI pressure range and the matching part number, but lacks detailed Mazda model fitment and lists no warranty.

NZMSMS states a 1,500–2,200 PSI operating range, its most concrete differentiator for buyers comparing direct-injection pump specifications. The listing also calls out turbo-engine compatibility and reinforced aluminum housing with hardened internal components, but its broad vehicle description still requires careful application checking.

The stated pressure range gives a specific performance specification to compare with the requirement for the vehicle’s fuel system. NZMSMS also describes the pump as suitable for turbocharged and high-performance engines, while reinforced aluminum housing and hardened internal components are presented as durability features. The listing references L3K9-13-35ZC and a broad 2007–2013 fit, but does not identify detailed make, model, or engine combinations. Confirm the actual application before relying on the general range.

Skip it if you need a stated Mazda model-and-engine fitment table; TRQ FPA53419 gives specific Mazda applications.

This may suit buyers comparing a pump by stated pressure range and construction details, especially for a turbo application. Its broad fitment wording is the boundary: establish the exact vehicle and OE match before selecting it.

9. Bosch 66811 GDI Pump

• Weight: 1.94 lb

Best for: OEM-style GDI replacement.

Why it ranks #9: Describes an original-equipment-style GDI pump and factory function testing, but gives no Mazda application or matching OE number.

Bosch identifies its 66811 as an exact-original-equipment gasoline direct injection pump, a concrete distinction for buyers seeking the same pump type used when a vehicle was new. The listing also cites operation under extreme temperatures and low-fuel conditions, addressing two demanding operating circumstances without supplying vehicle-specific fitment here.

Bosch says the GDI pump matches the original equipment specification, which gives buyers seeking an OE-style replacement a clear basis for comparison rather than relying only on a generic high-pressure description. Its stated ability to operate in extreme temperatures and under low-fuel conditions speaks to demanding fuel-system circumstances. Bosch also says every pump receives end-of-line function testing before leaving the factory. The supplied information does not identify compatible vehicles, so the part number alone is not a fitment confirmation.

Skip it if you need listed Mazda year-and-model coverage; TRQ FPA53419 provides specific Mazda applications for comparison.

Bosch’s 66811 suits buyers seeking an OE-style GDI pump with stated testing and demanding-condition capability. It is not a vehicle-specific fitment guide here, so establish application compatibility before treating it as the right replacement.

#10

10. URO Parts 07L127026AL Pump

• Weight: 2 lb

Best for: Quiet-operation replacement buyers.

Why it ranks #10: Lists durable construction and a 24-month warranty, but supplies no Mazda fitment; its brand description focuses on European vehicles.

URO Parts highlights precision bearings for quiet operation and reduced vibration, giving this pump a distinctive operating-comfort focus. It also specifies efficient fuel flow and pressure, durable housing and pump materials, and seals intended to withstand corrosive fuel and intense vehicle heat.

Precision bearings are presented as a way to reduce noise and vibration, which may matter to buyers focused on smooth pump operation. The efficient-flow design addresses fuel delivery, while the stated durable housing and pump materials support the product’s construction case. URO Parts also calls out seals made to withstand corrosive fuel and intense vehicle heat, connecting sealing materials to the operating environment. The supplied listing does not identify compatible vehicle makes or models, so fitment needs separate verification.

Skip it if you need a listed Mazda application; HAWK BROTHER L3K91335ZA specifies Mazda 3, Mazda 6, and CX-7 years.

URO Parts suits buyers prioritizing quieter operation, reduced vibration, and seals intended for harsh fuel and heat exposure. The listing offers no vehicle application details, so establish exact compatibility before selecting this pump.
