294050-0424 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 294050-0424, 97605946. Application recorded for this part: Fits Isuzu. The injection pump is what generates injection pressure and meters fuel to each cylinder in firing order. Because it also provides the timing reference, its condition affects starting, smoke, power and fuel consumption together — a pump that is worn rarely produces a single isolated symptom. Symptoms associated with pump wear include hard starting when hot, loss of power, unstable idle, excess smoke, timing that will not hold, and in some cases diesel getting into the lubricating oil via a leaking drive shaft seal. Confirm you actually need a pump. Verify supply pressure at the inlet, check for air ingress and restrictions, and have delivery and timing tested on the bench — many 'worn pumps' turn out to be supply faults. Fitting notes: timing is everything here. Set the pump against the engine's timing marks rather than forcing anything, prime thoroughly before cranking, and check that the lift pump is delivering adequate supply pressure. Also replace the mounting seal and confirm there is no air left in the system before the first start. Rebuilt rather than refurbished: full teardown and measurement, worn components replaced instead of cleaned and reused, sealing surfaces restored to specification, then bench calibration and testing. The record is what separates this from a used part — we can provide the test sheet for your order. Covered by a 12-month warranty.
