fearofweapons Posted September 3, 2019 Share Posted September 3, 2019 Hi, my wife's Series III with a 90 2.5 petrol webber carb'ed engine quite often stinks of petrol in the cab when its being driven. I do not think there is fuel leaking out around the carb - I have checked with it running and can see no drips. What is the most likely culprit for strong petrol fumes? cheers, Richard ( with a petrol headache ) Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 3, 2019 Share Posted September 3, 2019 Have you had a look at the top of the tank, under the seat? Quote Link to comment Share on other sites More sharing options...
2a-Egg Posted September 3, 2019 Share Posted September 3, 2019 If in the cab then def start at the tank, make sure its all sealed. If running Sat still have you had the bonnet up to check for split fuel line etc? Quote Link to comment Share on other sites More sharing options...
fearofweapons Posted September 4, 2019 Author Share Posted September 4, 2019 Thanks for the replies. Yes had it running stationary and checked the fuel lines - no splits or leaks found. Re the tank - what needs checking for being sealed? The pipe connections? What's the best thing to use to seal them? Cheers Richard Quote Link to comment Share on other sites More sharing options...

Cheers Richard The sender unit will be on the top, with spade connection on it, for your dash guage, that's a Cork seal, the you have the filler pipes, jubilee clips secure them. And the fuel pickup itself which will be a seal again cork or rubber I think. But if there is a leak then you'd see/ smell it once the seat is off I'd imagine Hope you find the issue Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 4, 2019 Share Posted September 4, 2019 If you don't see anything, then check the seams of the tank for leaks... Quote Link to comment Share on other sites More sharing options...
lo-fi Posted September 4, 2019 Share Posted September 4, 2019 If it's an 88, definitely whip the cover off the fuel filler behind the bulkhead and check that the filler pipe hasn't perished and split Quote Link to comment Share on other sites More sharing options...
fearofweapons Posted September 5, 2019 Author Share Posted September 5, 2019 Right some seals ordered and when they come I'll check the pipe as well. Don't know when I'll get chance to fit as life ( well death specifically ) is keeping us busy at the moment. I'll update the thread once I've done the work. cheers, Richard Quote Link to comment Share on other sites More sharing options...
fearofweapons Posted October 7, 2019 Author Share Posted October 7, 2019 So quick update.... Once I investigated properly I found that the fuel sender unit was not fastened down properly - it had a good 2mm+ 'float' up and down and was missing a screw; that may have been the main culprit. I have replaced all the seals leading into the tank and replaced the screws as the heads were a little chewed. After a test drive the smell of petrol is much reduced. Hurrah! 😀 1 Quote Link to comment Share on other sites More sharing options...
