faulty Solanoid

I have a VW Trident auto sleeper (rear 2L petrol water cooled engine) reg starts H169. It has started cutting out when warmed up at idle speed. Mechanic has fixed it, but doesn't know for how long, says I should try and get a replacement Fuel Shut Off Solenoid for the carburettor. Any one know if they can be obtained?

Thanks in advance

Last of the T25s from 1990 I assume? Loads of suppliers around - just use your favourite internet search tool. I've used Just Kampers before and they seem to have a good range of T25 stuff, but there are plenty of others. It's probably a bit too low-volume to get listed on supplier websites, so you'll probably need to phone a few.
