Walbro 460 High-Pressure In-Tank Fuel Pump (F90000274) – E85 Compatible

Unmatched Fuel Flow for High-Performance Builds

The Walbro 460 High Pressure Fuel Pump (F90000274) — also widely known as the Walbro 450 (Cross Reference – EFP-452) — is the go-to solution for high-power boosted applications running E85, ethanol, or high-octane fuels. Built for high-boost setups exceeding 30 psi, this pump is a proven step up from standard in-tank pumps like the Walbro 255, which run out of capacity once boost and fuel demand climb.

Built with dual-row turbine impellers, this fuel pump delivers:

• Lower current draw – 15A average, 22A max
• Quieter operation – Less noise compared to older gear-driven pumps
• Higher pressure relief (112psi) – Perfect for extreme boost levels

Vehicle Compatibility

Suits the following vehicles (along with many others) with minor cradle modifications:

• Ford Falcon BA, BF, FG, FG X & XR6 Turbo
• Holden Commodore VT, VX, VY, VZ, VE, VF
• Subaru WRX
• Nissan Skyline, Silvia, 180SX
• And many more high-performance vehicles
