Series 3 diesel lift pump

Faber · Jun 19, 2023

I dismantled this lift pump only to find that I cannot locate the t shaped diaphragm rod back in place using the spring.

If I leave the spring out there is no problem although the psi goes down to 4.

I can buy a new lift pump or fit an electric one but I would like to be able to fix this.

Has anyone had a similar experience or perhaps suggest a technique that works?

Thanks

It is a bit of a knack, with the spring it is not easy to feel the point where the T can be turned to lock.

I'll keep trying.

What about putting it back without the spring with 4 psi?

I have just managed to fix it, and I now have 7 psi.

Thanks for your input.
