Donaldson P551313 Fuel Filter — Spin-On Secondary

The Donaldson P551313 is a secondary spin-on diesel fuel filter engineered to deliver clean fuel to injectors and pumps. High-efficiency cellulose media removes damaging particles that cause wear, poor spray patterns, hard starts, and lost power. A rugged steel can, 1-14 UN thread, and precision gasket give a secure, leak-resistant seal. Collapse strength of 5.2 bar (75 psi) supports demanding on-highway and off-highway use. The spin-on design makes service fast: spin the old filter off, lube the new gasket, and install to spec. Always confirm thread, gasket size, and OEM application before ordering.
