Injector Leak-Off Pipe for the 2.25L and 2.5L naturally-aspirated diesel fuel injection circuit. This spill-return pipe connects the return unions on top of the injectors and collects the small volume of fuel that bleeds past each injector needle during operation.

It carries that excess fuel away from the injectors back to the return line. The pipe is a common perishable: once the connections harden or split they draw air into the injector returns, leading to hard starting and rough running, so it is renewed when servicing the injectors.

Frequently asked questions

What is the ERC4480 injector leak-off pipe used for?

The ERC4480 is an injector leak-off pipe, or spill-return pipe, for the 2.25L and 2.5L naturally-aspirated diesel engines. It connects the return unions on top of the injectors and carries fuel that bleeds past each injector needle back to the return line. Fits Land Rover Defender and Series 2/3 diesel.

What are the signs a leak-off pipe needs replacing?

A failing leak-off pipe causes hard starting and rough running. The pipe perishes with age and heat, and once the connections harden or split they draw air into the injector returns. It's a cheap fuel-system part that's typically renewed whenever the injectors are removed or serviced.

Do I need one pipe per injector or one for the engine?

One leak-off pipe assembly serves the full set of injectors on the 2.25L and 2.5L NA diesel, linking each injector return union in a single run. It's sold as one pipe, so you don't need a separate part for each injector.
