294050-0043 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 294050-0043, ME306386, 6M60T. Application recorded for this part: OE. 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. 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. 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.
