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.
