Overview – PUMP, FUEL/ CAPS PUMP 4954315RX
Engineered for Cummins fuel system as the CAPS (accumulator pump system) fuel pump, the Cummins PUMP, FUEL/ CAPS PUMP 4954315RX meets the tolerances your equipment was designed around.
Parts Characteristics
A CAPS (Cummins Accumulator Pump System) fuel pump that pressurises and meters fuel to the unit injectors, maintaining the high, stable pressure the injection event depends on. It is the heart of the fuel side, so a true, sealed pump keeps the injection timing and the power the engine was built around.
Applicable Models & Applications
Used on Cummins CAPS fuel routes specifying this pump. Match the drive, porting and pressure class against your old pump – CAPS pumps differ in how they feed and meter.
Maintenance & Replacement
Inspect the pump for weep at the shaft seal and the port seals at every fuel service. A pump that starts to weep loses pressure, and the lost pressure is what starves the injectors.
Replace the seals together with the pump where the kit calls for it. A new pump onto a reused seal still leaks, and the leak is what lets air into the high-pressure side.
Confirm the drive coupling seats true and to the correct depth. A pump driven off-axis cavitates and loses flow before the engine reaches temperature.
Keep the correct CAPS fuel pumps for your engine on the shelf. They are load-critical, and a fuel loop stopped on a pump is an engine waiting on a part.
