294000-0651 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 294000-0651, 22100-E0110. Application recorded for this part: HP3. Supply pressure, timing and delivery quantity are all set here. Failures tend to progress gradually — a little more smoke, slightly harder starting when hot, slowly rising consumption — which is why they are often attributed to the injectors before the pump is checked. 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. 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.
