Question type: Maintenance & Repair

My mechanic has looked for gas leaks and blew out all the lines to the gas vapor system right to the charcoal filter.   I dont know what to do next.   The smell is coming from the trunk area where the gas tank is.

There may be a vapor line off, or cracked behind the dash on the trunk/sid if the Dash.

Right by where the fuel filler neck goes into the tank there is a short vapor hose. Make sure that's not dryrotted.

I too have a 1979 volkwagen superbeetle convertible and had a problem with gas fumes. It turned out to be the fuel cap...it was old and the gasket had failed. I know this is a long time after you asked the question but maybe it will help someone else in the future.

I know this is an old post, but I too need help. My '79 super beetle stinks like gas. Wondering if you found a solution. I have had the fuel injection system gone through and it run so rich you can smell it and then it stalls itself out. Relay replaced, fuel lines cleaned, gas tank cleaned out, hoses replaced, timing checked. Fuel regulator tweeked, not sure where else to look
