PF9924 Fuel Filter Kit 4 Micron for DD-13 DD-15 DD-16 Trucks

Three elements and three O-rings: one coalescer filter, one final filter and one pre-screen filter. The set is sized for a single full service, not three separate changes.

The final filter is 4 micron rated, with 99% water separation across the kit. That is the stage that protects the high-pressure pump and the injectors.

Detroit DD-13 12.8L, DD-15 14.8L and DD-16 15.6L engines in Freightliner, Sterling and Western Star trucks, including Cascadia, 122SD, M2 112, Coronado and the Western Star 4700 to 6900 ranges.

PF9806 is listed as the equivalent service set, and the Detroit numbers A0000904251 and A0000901552 point to the same kits, along with P550954, FK48003, K10799, L5091F and 86849.

Drain the housing, fit the pre-screen first, then the coalescer filter, then the final filter, using a new O-ring at each joint. The pre-screen protects the coalescer from the larger debris, so the order matters.
