walbro 400iph hp in tank fuel pump only selling $209 shipped






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 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 >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




Walbro based the overall design on the same 39mm motor from the proven 255HP 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:


The Walbro 400 is a simple drop-in install for many vehicles such as nissan s13/s14 240sx, turbocharged 88-01 Hondas and Acuras, Mitsubishi Evo X 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 (we do not offer this currently). This pump uses the same plug as a traditional Walbro 255. External FPR strongly recommended
