Smell of Petrol

[Michel]

Over the last couple of days the inside of the car has a strong smell of petrol after being left standing overnight and during the day.

Smell disappears quickly after driving off and it doesn't smell of petrol whilst running...at least not that I can smell. I do get funny looks sniffing the car though.

No signs of fuel leak under tha car after its been standing, I tried it in the garage the other night with newpaper under the car to see if there were traces.

Is there a fuel vapour filter or breather that may have come loose in the engine bay or similar. With other cars that have had fuel system leaks the petrol smell was present when running in this case.

Its going to AmD for its service and MOT next week and want to get thsi sorted.

Thanks for any help.

one ive seen before on a 3B car was the breather fuel line under the car rotted through.

Take a look just left and back of the drivers wheel and you should see 3 pipes running back the length of the car, check these for any corrosion, damage etc.

Thanks for that.

Is it the same on a 94 ABY Avant? I'll try to see under the car later on.

Cheers.

I realise this post is super ancient but am hoping for some pointers to cure a very similar issue i hcauseave with my B3 engined S2.
Recently acquired it's in great order mechanically, extremely tidy but as Michel posted has a strong whiff of fuel in the cabin that seems to subside when the car is in motion. Nothing else is amiss, the car runs smoothly and the fuel lines show no sign at all of any corrosion or leaks.
I'm absolutely baffled as to the cause. It is in absolute mint condition with all unions perfect - no signs of rust.
Suggestions / or similar prior experiences appreciated.

Check the seal around the plastic cap that seals the pump in to the tank. I had a smell of fuel also and the seal had perished.

Thanks for the pointer RustyNut. I'll check this seal out. Easy to source a new seal?
Cheers.

Mine was about four quid from the stealers I think.

Thanks again Rusty - seems a problem experienced by a few folks:-

Update...Hardly driven but since filling the tank and taking it on a decent trip the fuel 'whiff' has mysteriously gone. Maybe a blocked breather, i'm unsure. Thanks for the pointers - will keep them in the mental toolbox should the issue resurface.

Petrol fumes.

Check the seal around the plastic cap that seals the pump in to the tank. I had a smell of fuel also and the seal had perished.

Glad somebody posted this as i have same annoying problem with our very late final edition cabriolet and this fix will i am sure be the problem as its inside the car, hence fumes in the cabin.Probably all our old auids should be checked as a precaution
