Fuel smell when hot
Discussion
Last few times I've been out in the chim I've noticed a fairly pungent fuel smell when travelling at low speeds (I.e in traffic). Only seems to occur when the engine has been running hot enough for the fans to have cut in and doesn't occur (i think) when running cooler.
Had a quick poke under the bonnet and all seems ok. High pressure fuel lines look virtually new (only had car just over two months). Don't really know what else to check.
Suggestions gratefully received.
Cheers!

Thas exactly how mine first started out a while ago. I could smell a faint whiff of petrol when at a standstill or slow moving and then it got a little stronger. I looked under the car and could see petrol running down the exhaust!!!!
It was the fuel hose, it had split just at the join with the copper fuel pipe.

Yep, that's the kiddie!! Mine had split just at the top of the copper pipe. It's actually a really easy job. I removed the plenum (6 bolts) and just swivelled it out of the way. a small ring spanner and a long screwdriver will help you get to the jubilee clip at the top of the pipe, best accessed from the passenger side. My original pipe was quite tight, it's worth allowing an extra few inches to keep the bends nice and loose and away from rubbing on any pipes etc.
Gents, thanks again for your suggestions. Cleaned up fuel hoses from fuel rail yetserday and primed the pump a couple of times. Dry as a bone I'm pleased to say, so started car and no signs of leaks.
Possible slight leak from filler cap but hose to tank also fine.
Did notice that number 8 ignition lead seems to want to break free at any opportunity (doesn't seem to clip on properly) so wondering if that might be the culprit although car felt fine.
Anyway, since inconclusive, it's going up to Bespke Performance for a quick once over - just in case.

Not sure on the why this works or indeed how b ut I do know it certainly worked on my Grif. Great article thanks to Clivef and a donation to a worthy cause and your away. Fume smells a thing of the past, unless of course the problem is caused by a leak. HTH

Thanks roseytvr. I was posting about fuel smells rather than normal exhaust fumes but I have that problem as well so this is now on my list!Not sure on the why this works or indeed how b ut I do know it certainly worked on my Grif.

Bespoke Performance had a good look and fettle with my car today and all is now well. Fuel system in rude health and car running beautifully. Very good experience all round in fact.

My old Chimaera had the same issue as yours. Everything was checked but could never find the source of the smell!Possible slight leak from filler cap but hose to tank also fine.

I think you can get a whiff from the carbon canister occasionally as it vents to atmosphere.
Speaking of which I was adjusting my offside headlight the other day only to find the carbon canister lying in the bottom of the wing. No idea how long its been bouncing around in there. Have to repair the clip that holds it in place.
