294000-0039 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 294000-0039, 97306044. Application recorded for this part: Fits Isuzu. 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. Check supply pressure at the pump inlet and look for air in the clear line before assuming internal wear. Plenty of pumps get replaced for a blocked filter or a suction leak that costs a fraction to put right. Set timing to the engine’s marks and never lever the pump into place — bar the engine over instead. Prime thoroughly, use a new mounting seal, verify lift pump supply pressure, and bleed before starting. A dry start is the fastest way to ruin a 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.
