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. We offer a good quality metal canister filter (disposable) with 3/8-inch hose barb ends as well as the outstanding Holley aluminum billet 390 LPH filter with -6 and -8 AN fittings. The Holley filter can be disassembled and cleaned or the entire filter media renewed.
