The Walbro 400 lph in-tank high pressure fuel pump is a brand new aftermarket release. Designed to meet the fuel-hungry demands of modern turbocharging enthusiasts the Walbro 400lph high pressure unit can flow close to the amount as dual intank pumps or large externals but in a small, convenient and surprisingly quiet package. This pump is a great solution for high fuel requirement turbocharged cars 500bhp and anyone looking to make big power and run high boost with a simple fuel system where the 255 won't suffice. This much fuel flow is not meant for use on engines 400bhp.
Walbro based the overall design on the same 39mm motor from the proven 255lph pump but changed from a "gerotor pump" to a newer and more efficient turbine pump.
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:
