Product Detail
Electronic Unit Pump (EUP) 1668325
1668325 is an electronic unit pump (EUP) supplied as a replacement fuel injection unit pump for diesel engine applications. In an EUP system each cylinder has its own camshaft-driven pump feeding a short high-pressure line to the injector, so the pump is replaced as a complete unit.

Why Unit Pumps Are Replaced
The pumping element and delivery valve wear against their seats with every camshaft revolution. As they wear, the injected quantity drifts and the ECU compensates until the correction limit is reached. Drivers notice hard starting, a rough idle, falling power and smoke, and the fault is often accompanied by a cylinder-balance code.
Fitting Notes
- Confirm the number on the original unit before ordering; EUP pumps are matched to the engine variant.
- Keep the high-pressure line and pump bore clean and use new sealing washers.
- Recode the unit where the engine management requires it.
