About this part
104649-5471 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 104649-5471, 104749-5482, 8971366832, 9F1250LNP1592. Application recorded for this part: VE4.
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.
The pattern is normally cumulative: slightly harder starting, then noticeable power loss, then smoke and unstable idle. Where the drive seal has failed, diesel in the lubricating oil is the warning that should stop you running the engine.
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.
What we do differently: every core is stripped to components, inspected against wear limits and measured before anything is reused. Worn parts are replaced, not cleaned and refitted. After reassembly the unit is bench-tested — delivery, return flow, opening pressure and leakage — and only units inside specification are dispatched. We can send the test sheet for your order before it leaves. Every remanufactured unit carries a 12-month warranty.
