The Walbro 400lph "turbine style" High-Pressure fuel pump is a brand new aftermarket release for 2011. Designed to meet the fuel-hungry demands of modern turbo-charging enthusiasts the Walbro 400lph High Pressure unit can flow close to the amount of dual in-tank pumps or large externals but in a small, convenient and surprisingly quiet package. This pump is a great solution for high fuel pressure turbocharged cars and anyone looking to make big power and run high boost with a simple fuel system where the 255 won't suffice.
Walbro's turbine pump head uses two sets of turbine blades set in parallel on a common shaft (like a jet engine). This high efficiency 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 and to suit various injector sizes.
Due to the specifications of this fuel pump, please take note of the following:
The larger diameter at the base of the fuel pump will prevent this from being an OEM drop-in replacement on most applications. Modifications to the mounting bracket, wiring, and connector may be required for proper fitment. We recommend 14 AWG wiring to account for the current draw this pump has.
