S1 cooler on the fuel return
Discussion
NZDave said:
I have once had a fuel vapourising problem with my '87 S1. This was on a long steep hill in very hot conditions and a gradual misfire crept in. This got worse until the thing stopped and wouldn't refire. We finally got it going by turning around and jump starting it while running down hill. I found out about these fuel coolers then but never got around to doing anything about it. I have not had the problem since but have not been in the same conditions either.

Had the same problem in the Alps (Tsjimmeljoch) on a very warm day. My solution was to loosen the connection on the fuel filter a second to let the vapour escape. The day after (same warm conditions) we insulated the fuel lines and pump in the area of the fuel tank /exhaust and drove up hill on the Stelvio without any problems.Dave
