CAV fuel pump.

Hi all, I got the old ninety 2.5 tdrunning yesterday and it was spewing fuel out the old cav fuel pump!
Needs an overhaul! Anybody selling kits for them?

Any idea where the fuel is coming from?

Yip the rear of the pump where the injector pipes cone t! If you go towards the front of the pump there's is a plate/shim which attaches to the side of the engine! Well that's lose and turns a bit and diesel o's coming from there!

Have you checked the high pressure lines themselves? Sometimes the unions leak or the union nut splits.

If you mean the pump is loose on its mountings it needs tightening up and timing check.
Bit of diesel? Is that a tiny weep, or a steady stream, and are you sure it isn't running over the pump body from the other leak? A little bit of hot diesel goes a long way!

The pipes where all new parts and I checked the nits for splits/cracks and they all tightened up and dried up! The pump was tight but the timing was of as the engine was lumpy but might be down to lack of fuel. I've started to remove the pump and I'll look for a replacement or for someone to refurbished it!
