Lucas epic rotative pump

Unread post by Fabietto »

Hi, the citroen 2.1td of the early '90 got the Lucas epic pump and is very common that pump leaks fuel from the gaskets.
Here on the forum i found the best tutorial of all the web for refitt the pump by Jim Eastment (thks too much)but i don't understand one thing:
-if i want change just the main gasket,when i reassembly the pump, does i must set up the timing injection pump?
if i change just the main gaskets, is it not mandatory to set up the rotor timing?
Sorry for my english
Thanks

Hopefully Jim will see your post and let you know the way to do it! :-D

Hi Fabio and good t o see you here :D Sorry for the delay in responding; I was away yesterday.

No, when you just replace the gaskets and seals there is no need to set any timing. All you need to do is position the pump on its engine mounting bracket exactly as it was before you removed the pump.

Timing is under full electronic control. It is always a very good idea to check the Needle Lift Sensor (part of one of the injectors - the one with a thin wire connected to it) is working properly. They often fail and upset smooth running of the engine...
