Walbro's 450 LPH E85 compatible "turbine style" in-tank High Pressure fuel pump is the single highest flowing Intank pump we offer. Designed to reliably meet the fuel-hungry demands of turbocharged gasoline high performance engines, this pump is remarkably quiet and heats fuel less, due to the turbine rotor design. Walbro Engineers based the overall design on the same 39mm motor from the proven 255HP but changed from the old "gerotor pump" to a high performance "Turbine pump". They also revised the motor assembly to allow for PWM fuel pump control or standard +12V. The turbine pump head uses two sets of turbine blades set in parallel on a common shaft (like a jet engine). The pump design pressurizes the fuel as it flows through the pump axially, without forcing the fluid to change direction - the end result is tremendous flow rates at a variety of different rail pressures.

Walbro 450 Fuel Pump Features:

  • Outperforms most in-tank fuel pumps, including the walbro 400
  • High pressure, high-flow performance found with the unique "fat-bottom" pump mechanism, flows 416 LPH at 12V, 450 LPH at 13.5V
  • Award-winning OE technology for consistent performance and reliability
  • OEM technology designed and developed for E85. All pumping components have been validated to OEM specifications for approved use in E85/flex fuel applications.

This pump is a great solution for high fuel requirement turbocharged cars >500hp and anyone looking to make big power and run high boost with a simple fuel system where the 255 won't suffice.

OD (large): 50mm
OD (small): 39mm
Flow rate: 450 LPH @ 13.5 Volts / 416 LPH @ 12.0 Volts

Kit includes:

pump, wiring, filter sock and a small section of fuel hose.

Good gift
I got this as a gift for My boyfriend. He is a mechanic that means he’s always working on trucks. It’s always in his pocket and has been through a lot and it’s still holding up.
