Hi,
I have a really persistent fuel smell in my 1978 SC which I’m unable to resolve. The car has gone through a complete restoration so all fuel lines etc have been replaced.
When I pressurised the fuel tank through the fuel tank ventilation outlet I noticed that air was coming out of a hole in filler neck. This hole looks like it is supposed to be there. On the inside of the filler neck there is a tab covering the hole. My guess is that it is closed by the fuel cap and open when the fuel cap is not in place and putting pressure on the tab. Mine is leaking even if the fuel cap is in place though.
Can anyone confirm if this hole really is supposed to be there and if so how does it work?
Sorry about the rather poor pictures, difficult angle to get a good shot.
Thanks!
