Genuine Fleetguard FF5421 Fuel Filter | Cummins 3978040 | Baldwin BF7966

Genuine Fleetguard FF5421 Fuel Filter

The can is a genuine Fleetguard printed FF5421 with the Cummins number 3978040 and a block of Chinese text on the wrapper, plus 800138191 written on it by hand. That hand written number is an XCMG service number somebody wrote on the shelf so the part could be pulled for a machine order. The printed Fleetguard number is what governs, and this is FF5421.

FF5421 is a spin-on fuel filter, not a fuel water separator. It is worth stating plainly because we carry a second listing under the XCMG number 800138191 that describes this same physical part as a separator, and that description is wrong. Treat FF5421 as the fuel filter number.
