Default Gas odor

After a drive in my 65 Fastback, I smell like I rolled around in a puddle of gasoline. My garage also has that gas type odor. I have checked fuel lines and behind the carb for any leaks, but could not find any. I also checked the filler pipe and it appears to be ok. Does anyone have any suggestions?

Could an exhaust leak account for this? Although, I guess if it was an exhaust leak that wouldn't account for the smell when the car is not running.

Thanks.

when mine smelled like gas it was the fuel line running to the fuel pump.

I had the same and when i changed the flexi-pipe from gas cap to tank although it looked fine on the outside inside it was cracked and now the car smell much better. So it may not be your problem but it's a cheap fix worth trying.

Thats what charcoal canisters are for, theyre meant to trap gas fumes and recirculate them. I dont think your car is equppied with one, being a classic. I believe 1973 was the first year it was mandatory to have charcoal canisters and cats.
But definitly check your fuel lines/tank etc. if the rubber lines are hard (like pastic), they need to be replaced, and it being such an old car it wouldnt be a bad idea to replace all the lines anyway. Like someone else suggested check the rubber seal going to the tank from the filler neck, even though it might not appear to be bad, it probably hardened up, and isnt creating a good seal anymore.

Thanks - I'll change the lines. They look fine, but probably are pretty old. Guess I should go ahead and replace the seal at the filler neck too.

Carb could be running too rich as well. That would give you some smell.

I do not have a seal where the cowl meets the hood - never noticed it was missing. I better get one on there.

As far as running rich, the car probably is. When I start the car and give it gas I leave pretty good size black mark on the concrete below the exhaust tips. Does running rich mean the carb is getting too much gas? Thanks.

I got my answer on what running rich means - found lots of info using the search feature. Sounds like I better leave carb adjustment to an expert.

Yeah, sounds like you are running rich. You can adjust carb yourself. Not hard. Just get a shop manual and follow directions.
