Fleetguard Secondary Fuel Filter - Volvo D11/D13/D16 & Mack MP7/MP8 Pre-2017 - Replaces 20430751 Baldwin BF7814 FF5507

The Fleetguard FF5507 is the OEM secondary, or final, spin-on fuel filter used on Volvo and Mack Class 8 trucks, and it is the last thing standing between your fuel tank and a set of injectors. It protects the high-pressure fuel system from the fine contamination the primary filter lets through, and when it is neglected the truck tells you: fuel restriction, low power, and injector damage that costs many times what the filter does. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Final-Stage Filtration: The FF5507 Advantage

This is Cummins Filtration's own captive-brand filter, engineered to Volvo and Mack OEM spec and installed both on the assembly line and across the dealer service counter. The cellulose media runs outside-in for final-stage duty on high-pressure common-rail and unit-injector systems, and the can is built to the factory envelope: M32 x 1.5-6H thread, 10.39 in (263.9 mm) height, 4.24 in largest OD, and a 3.94 in / 3.56 in gasket. It spins onto the pre-2017 Volvo and Mack filter head with no adapter.
