About this part
5462094 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 5462094, 5462079, P5462079. Application recorded for this part: Fits Cummins — ISZ.
Every injection event depends on this pump producing pressure at exactly the right moment. Because it also carries its own lubrication, poor supply pressure and fuel dilution do disproportionate damage — which is why the supply side should always be checked alongside the pump itself.
Look for extended cranking, especially hot, poor throttle response, smoke across the rev range, fluctuating idle speed, and a gradual rise in consumption that cannot be explained by duty cycle.
Diagnose the supply side before blaming the pump. Restricted filters, a tired lift pump or air being drawn into the suction line will produce symptoms almost identical to internal pump wear, and are far cheaper to resolve.
Key points: align to the timing marks rather than forcing the drive, prime before cranking, renew seals, confirm adequate supply pressure from the lift pump, and bleed the system fully. Skipping any of these is where most comebacks originate.
Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
