Walbro’s 400 LPH “turbine style” in-tank High Pressure fuel pump is designed to meet the fuel-hungry demands of turbocharged gasoline high performance engines. The Walbro 400lph High Pressure unit can flow close to 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 >500hp 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 <400hp.

The Walbro 400 F90000262 is a simple drop-in install for many vehicles such as nissan s13/s14 240sx, turbocharged 88-01 Hondas and Acuras, Ford EcoBoost and many more. GC and GD subarus can use this pump, although certain year STI’s will want to remove the STI fuel filter (intank) + swap to WRX filter on firewall. Modifications may be required for certain vehicles due to the large 50mm base – Evo8/9 and 2006+ Hondas will require slight modification to the stock housing. This pump uses the same plug as a traditional Walbro 255.

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:

A Universal Installation kit is available separately (not needed for all installations). The Install kit contains Fuel Filter, Wiring Harness, Butt Connectors, Hose Clamps, Fuel Hose and Precautionary Statement Sheet.

Running E85 or other ethanol fuels? We also offer the Walbro 416 lph, for E85 applications which require even more flow than the 400lph can dish out.
