Full Race Walbro 400lph 39/50 DCSS Hi-Perf In-Tank Pump
$115.50
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.

Specifications:
  • OD (large): 50mm
  • OD (small): 39mm
  • Length: 121mm
  • Flow rate: 400 LPH @ 40PSI @ 13.5 Volts
