Thanks Drivers,

I read that about the fuel heat exchanger, think ours is ok at the moment.

Just put new Viton O-rings in the Lucas pump so it'd no longer weeing Diesel everywhere. I still don't get how the purge clears the air then goes firm, but it works.

How many 90HP XUD7TE's have found their way into 205's?

Cheers

Tim

Hi Tim,

Many people have intercooled the XUD7 but the 'usual' engine swap is for the XUD9TE.

Can't speak for the Lucas system (I think its the same though) but the Bosch pump is fitted with a hollow bolt+banjo for the return with a 0.5mm hole in.

This is fitted to the upper part of the pump housing to A- Help expell air.
B- Regulate pump case pressure.

So when you prime the system the air escapes through the hole till its removed, you are then trying to pump liquid through the same orifice. This is why it goes hard..... Oooh err :)

Uber,
Don't know about the .5 hole, but our pump exit banjo has a non return valve, which works when I suck'n'blow,,,,oooer again.

 

My old 405 was a 1.9 with intercooler, must have had the 9TE, should have kept it eh? Cars wernt on the radar back then.

 

Ozy,

missed your post on Haynes, too late I bought a pair off fleabay for a couple of quid each, I never read the things anyway, just write stuff in the cover.
