Note: This pump should never be operated without a fuel filter between the tank and the pump. This pre-filter should be 20- to 40-microns. Additionally, almost all applications require a 10-micron post-filter between the fuel pump and the fuel rail. Putting just a 10-micron filter before the pump is not recommended. Also, due to the nature of the use of this pump, no warranty is available.

The Walbro 400-939 installation kit includes two standard universal hose barb fittings designed to be used with high pressure 5/16" fuel hose.
