Overview – END CAP-FUEL TANK 159-1645
Engineered for Cummins fuel-tank positions as the fuel-tank end cap, the Cummins END CAP-FUEL TANK 159-1645 meets the tolerances your equipment was designed around.
Parts Characteristics
A fuel-tank end cap that closes and seals the tank end, keeping the fuel in and the contamination out at the tank itself. It carries the seal and the vent path, so a correct, sealing cap keeps the tank closed and the fuel clean.
Applicable Models & Applications
Used at Cummins fuel-tank positions specifying this end cap. Match the bore, the seal and the vent against your old cap – tank end caps differ in how they seat and vent.
Maintenance & Replacement
Inspect the cap for a hardened seal and a cracked flange at every fuel service. A cap that has begun to weep lets water in, and the water is what rusts the tank and the lines.
Replace the seal with the cap where the kit calls for it. A new cap onto a flat old seal still weeps, and the weep is what stains the bay.
Confirm the cap seats and the vent is clear on fit. A cap cross-threaded or a blocked vent either leaks or starves the pump.
Keep the common fuel-tank end caps for your application on the bench. They are cheap, they protect an expensive tank, and they are exactly the part missing when a tank needs closing today.
Price Reference (USD)
Budget roughly USD 5 to USD 30 for a END CAP-FUEL TANK 159-1645; volume orders and stock status can move this range either way.
Value & Service
