Hi guys and gals, time to grovel and accept that saying my P38 was ultra reliable was tempting fate. Driving around I've found a really strong smell of fuel building up inside if we've the windows open, back ones in particular. It was so bad yesterday I felt sick. I've crawled under, over, round and round but can't find a leak in petrol or gas systems-with the engine running and warmed up. The only thing I can find is a smell of petrol near the filler cap, which I assume is from the tank vent. Any ideas please?
