About this part
3916987 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 3916987, 0460426174, 12F1300R37, 6BT118. Application recorded for this part: Fits Cummins — VE6 7-1 5.9L.
This pump has two jobs that are easy to conflate: raising fuel to injection pressure, and metering the correct quantity at the correct moment. Wear affects both. The result is usually a combination of harder starting, drifting timing and visible smoke rather than one clean fault.
Typical indicators are progressively harder starting, particularly when hot, reduced power, smoke under load, erratic idle, and fuel dilution in the sump — the last one should always be investigated immediately.
Before condemning the pump, rule out the cheap causes: supply restrictions, a weak lift pump, air ingress on the suction side and a blocked filter. Check supply pressure and condition at the pump inlet first, then look at delivery and timing.
Installation notes: never rotate the pump by force to align it — bar the engine over instead. Prime before cranking, renew the drive seal, confirm supply pressure, and bleed the system properly. Dry running for even a few seconds is the most common cause of premature failure on an otherwise sound pump.
Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
