Description
Genuine Walbro F90000274 450LPH E85 Fuel Pump for Performance Builds, Authentic Walbro / TI Automotive
If you are building a forced-induction or high-output naturally aspirated engine, the Walbro F90000274 is the de facto standard upgrade for in-tank fuel pump platforms. The pump delivers 450 liters per hour at 40 PSI (nearly double a typical OEM pump), with full E85 ethanol compatibility that allows the use of high-octane ethanol fuel without destroying the pump internals. Common application platforms include Subaru WRX/STI, Mitsubishi Evo, Honda K-series swap builds, Mustang GT, Camaro SS, and most other in-tank platforms running serious power.
Vaz Auto Solutions sources Walbro F90000274 pumps through authorized Walbro / TI Automotive distribution. Every pump arrives in unopened original Walbro packaging with holographic authenticity sticker, manufacturer barcode, and serial number traceable to the manufacturer. This protects you from the widespread counterfeit pump market where fake F90000274 units fail rapidly and lack E85 compatibility.
Order with confidence at $189 for the base pump, with QFS install kit option available as upgrade for customers needing fresh strainer, boot, connector and hardware.

Caleb Whitmore –
Bought the F90000274 for my 2018 STI build (target 550 HP on E85). Vaz was extremely upfront that this is a brand-new aftermarket performance part not used OEM (different from their main business) which I appreciated. Pump arrived in unopened Walbro packaging with the holographic sticker intact and the serial number traceable. Added the QFS install kit option for $20. Installed myself with rear seat access on the STI. Pump runs perfectly, flow rate verified by my tuner against the spec. Best par
Jasmine Okafor –
Picked up an F90000274 for my Honda K-swap build (K20A2 in an EG hatch, turbo, E85). Vaz confirmed the pump dimensions matched my AEM in-tank assembly. Authentic Walbro packaging, holographic sticker present, serial number on pump body verified. Tuner dialed in the fueling without issues, pump easily supports my 480 HP target. One star off because the QFS kit option timing took an extra day to ship (kit needed to be added after my initial order), small logistics issue but everything else perfect
