Hi Marty,
Fuel dripping just after you get home, or after sitting over night? Regardless, you don't want fuel vapor building up in your garage!!
I see you only have a few posts on the forums. Do you have much knowledge or experience with the fuel system on these cars?
You could simply have a rust hole near the top of the tank. How long have you owned the car, and do you know if the tank is factory original or was replaced at any point?
The fuel hose at the station should stop before "over filling". There is a hole in the top of the tank where the "sender" is mounted. It reads and sends the fuel level in the tank to the fuel gauge. It has a cork seal. If that's really old, and the tank is over full, then I suppose it might leak some and create a drip.
There is a venting system for the fuel tank - the gas cap is not a venting cap. I don't know if vapor would condensate and drip from a faulty venting system.
If you like looking up info and learning on your own, our search function works great. See attached. It would be best to search in the sub-forum pertaining to fuel system.
Are you a handy mechanical person who tries to fix things yourself? Removing the fuel tank is not the hardest job on this car. We can advise and help. As with anything on these cars, once you start to dig into an area to fix one problem, you might find three additional problems. If you pull the tank, you might end up replacing fuel lines, vent lines, the filler neck seal, etc.
