Strong Fuel Smell.... Options

[quadracerx]

My 76 Red car got converted to dual Webers before I bought it...Since ive owned it, it has always had a VERY strong fuel smell after running it for awhile....It has the expansion tank still on it. If it sits for a couple days no smell....checked lines and tunnel and no visible leaks...no leaks under car....Im stumped...

HELP the smell is so bad that it lingers long after shutting the car down......It even makes my clothes smell just from running the car...

Thanks again, everyone (IMG:style_emoticons/default/beerchug.gif)

I have had fuel smells, been through the whole system several times, and just discovered recently on my car then on 2 other fuel tanks at my buddies 914 stash the following..


From the fill cap there is a small metal tube that the hose to the expansion tank connects too. On all 3 fill necks of the tanks I looked at including mine the metal tube wash pinched shut on one end, thus not allowing vapors to escape via expansion tank desighn.. I opened mine back up, and thus far I have had no smell. I used to
at times usually with full tank or steep incline or stop and go traffic summer get the smell and it would not leave for a couple days.. depending.

I would not start to dismantle the re-evaportation system but I would make sure it is connected properly and in good condition..

Also have you pulled your fuel tank yet? You do not need a visible leak from under the car to get the smell. A small amount is enough, then it evaporates.

Fuel smells are a sighn something is wrong, fuel leaks can be dangerous so it would be best to investigate the entire system before jumping to conclusion solutions.

I feel you on the disconcerting fuel stench, It takes away from the 914 experience when passenger think what a heap burning fuel oil...

Diagram Below.. is for the 3 port fuel pump, you get the idea though and need to check all lines, fuel pump and connections ect. including under the fuel tank nipples, also some fuel tanks develop rust pin holes where the tank sits, there are 3 glued in foam rubber pads under and on side of tank (not the 2 you can see while tank is installed) that tend to hold water and create rust bubbles, potential holes ect, good to inspect those too.. I replace those with solid rubber while the tank was out..
