XUD (Lucas) Boost Diaphragm.

Post by treky9.9 »

Having a lot of fueling issues with my 306 TD (1.9, 1995, 224K). I am pretty confident that it is the boost diaphragm, as I have been making small adjustments for a while and the 'lack of power' or 'smokey' symptoms change accordingly.

The pump is a Lucas one with the aneroid disk on the front of the pump.

My questions are:
1. How easy is it to replace
&
2. Where/who can I get one from?

My thank you in advance for any help you may be able to give me.

When you increase the fuelling you also need to increase the turbo boost, without you just get more smoke and less fuel economy.

Thanks Sparky, I am pretty sure that the turbo boost is ok. I am having some strange issues with the fuel adjustments and would like to replace the diaphragm unit.

So am still looking for info regarding my original post.
