About this part
10516082003 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 10516082003, 1000161361. Application recorded for this part: 10516082003=1000161361.
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.
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.
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.
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.
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.
