0445010851 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 0445010851. Application recorded for this part: F250 F350 F450 F550 6.7L. 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. 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. Eliminate the cheap causes first: filter condition, lift pump output, suction-side air leaks, fuel quality. Only then have delivery quantity and timing tested before committing to a replacement unit. Key points: align to the timing marks rather than forcing the drive, prime before cranking, renew seals, confirm adequate supply pressure from the lift pump, and bleed the system fully. Skipping any of these is where most comebacks originate. 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.
