Description:
PP-4944404 Cummins 4944404 / 3897517 / 5288253 Fuel Cooler
This Seakamp Fuel Cooler is a marine-grade replacement designed for Cummins marine diesel engines used in commercial fishing vessels, workboats, sport-fishers and pleasure craft, most commonly fitted to the QSB, QSC, QSM family. The unit has a 3/8" Dia core. It also replaces Cummins part #3897517 and #5288253.
Modern common-rail and high-pressure diesel injection systems return excess fuel to the tank at elevated temperature. The fuel cooler routes that return fuel through a tube-and-shell core where raw water carries the heat away, preventing fuel-tank temperature build-up and protecting injector clearance, lift-pump performance and overall fuel-system reliability.
Sustained high return-fuel temperature can degrade fuel-tank seals, raise injector clearance, reduce engine power and trigger overheat protection. A correctly functioning fuel cooler protects injector longevity, supports rated power output and prevents derating in extended high-load operation.
Manufactured to match OEM dimensions, port orientation and mounting geometry, the 4944404 is a true direct-fit replacement for the original Cummins component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing.
