Another question. My fuel tank has a vapor outlet. Currently it is just open. I assume it should have a pipe on it to take the vapor somewhere. My 1968 G60 doesn't seem to have any emission controls on it. So where should the vapor pipe go? Also surely in hot weather the petrol will just vaporize! Can I close of the vapor outlet or will it cause problems?
The vapor outlet (also ventilation) will connect back to the filler neck. See any of the parts catalogs and you'll see it very clearly. The following is from an online parts manual:

If you block this outlet, it will be very difficult to fill the tank, since the air displaced doesn't have a good way to go. Please note also that the pipe connection at the filler neck is probably clogged with debris sent by the wheel if the hose was not attached there.
