I've been working on my 74 Superbeetle convertible since I bought it in January. It is running great! When I fill up he gas tank there is a STRONG smell of gas coming from the tank area. No leaks that I can find. Funny thing is, the smell goes away when the tank gets to be about half full. Any ideas?

 

tank should be vented so i would guess your just getting a whiff of the vent tube .. mine does it too

 

mine used to do it to the vent lineis hooked up to the main fuel line the fill line. it had some crappy cloth like hose on it about 1/8 inch and when i filled up,it would slosh thru the line and saturate the vent line and man did it smell .

 

mine did this too what i did to fix this problem was to change the line for my ventulation

 

Worked on those things long ago at a dealer, and also had my
own VW shop for years, That gas smell your getting is the vent
tube, they should be replaced and vented under the car, if you
look closely you will find a small hole for the tube to fit into and
exit the vapors under the front of the car, also the gas cap will
get a bad seal and you will get vapors there.
