Fuel tank overflow?? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

When I fill the fuel tank right up (and i mean completely full!), then i get into the car the fuel gauge shows that it is overfull. Thats fine, but after about 1 minute fuel starts to leak out from above the front right corner of the tank. I believe that is the location of the environmental protection valve or something (??). It is mostly a steady quick drip and is particularly bad when the car is stationary for longer than a minute. This dripping doesn't stop until the fuel guage shows the tank is just below full. I have been told that my brother's friend who has an ED falcon can fill his car right up and it wont leak at all. So was there a design change between models? or do I have a minor problem to fix? I would be interested to know if anyone elses car does this.

Thx.

I was told that its bad to fill a car over full with fuel. And i'd assume that EFI's are worse, cause there would be more fuel pressure.

Maybe you have a vent or something that is blocked....

Sounds like you have a leak where the vent hose joins the tank. Or it might be leaking where the vent hose joins the filler pipe and running down the outside of the vent or filler pipe to the tank and appearing to be leaking elsewhere. You should be able to full the tank to the top without any problems.

You have a leak somewhere and need to fix it ASAP; when liquid fuel isn't leaking out evaporated fuel vapour is and this is just the stuff to get a car fire or fuel tank explosion.
