Walbro 400 LPH Fuel PUMP

Walbro 400 LPH fuel Pump

Walbro has just released a new 400 lph fuel pump and we are happy to bring to you some information about the new fuel pump.

1. It is larger than the 255 lph pump so it will not be a direct drop in replacement for a walbro 255 if thats what your replacing.

2. It flows a lot of fuel, but as the fuel pressure goes up the flow starts to take a dive, so for you boosted guys out there running 60+ fuel pressure on your 1:1 Fuel Pressure Regulators, just be careful about of running out of fuel. Check the charts below and calculate how much flow your actually going to need at your given fuel pressure.
