1001620056 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 1001620056, B6AD548G11-R, BH6PN120R. 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. Expect extended cranking especially when hot, hesitant throttle response, smoke that persists rather than clears, timing that drifts or will not hold, and in some cases fuel in the sump or a pump body running unusually hot. Diagnose the supply side before blaming the pump. Restricted filters, a tired lift pump or air being drawn into the suction line will produce symptoms almost identical to internal pump wear, and are far cheaper to resolve. 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.
