Tell you what..

You can try clamping the fuel return pipe to test if the increased fuel pressure at the Carb improves performance. Some people block off the return pipe completely (and remove the "T" piece) which is acceptable provided you block the return pipe to tank in a very secure manner with no risk of spillage (even if the vehicle is inverted) or vapour escaping..... It is worth noting that the "T" piece has a restriction built in (on my 1991 model at least), i.e. one of the pipes is much smaller internal diameter than the others. This is the case on my 1991 Vehicle and the narrow pipe is the one to which the return pipe to the tank attaches.

This is an issue that had a lot of discussion on other forums.
As the van is fairly new to you, check that the fuel return pipe hasn't been replaced.
If it's a much wider diameter than the original, it causes poor running as there is too much unused fuel being returned to the tank.

So does it sort of starts misfirng then gets progressively worse until it becomes undriveable?
No just starts kangaroo-ing sometimes will go again in seconds, sometimes will die as in fuel starvation. Wait no more than 30secs - 1 min and it may well restart and run OK for a while.

No it's still on the original (as far as I can tell) pipe which is 6 or 7mm and not the usual 8mm. I now have a clip on the return pipe and I have throttled it down slightly.

It's still doing it. Drove down to Argeles-sur-mer via Frankie's and it is still dying on me occasionally. Time for new fuel pump? If I can get one, or do I go electric?

Sorry, Movan, forgot to give Frankie a hug on your behalf.:Doh:
