Description
The Fleetguard FF5021 is a 20-micron primary spin-on fuel filter for Detroit Diesel two-stroke engines (53, 71, 92 Series and 8.2L Fuel Pincher), replacing Detroit Diesel 23530640, Motorcraft FD789, Caterpillar 9Y4419, and Ford E1PZ9155A. The 13/16-12 UNS-2B threaded base and short 4.31-inch standpipe-free can fit OEM mounts on older Ford F-series and GM trucks with the 8.2L diesel, GMC heavy chassis, and a wide range of Detroit-powered industrial equipment.
