Last Friday Rich and I replaced the broken fuel filler pipe and realised that the same thing would happen again. The new fuel tank we ordered was simply the wrong shape. It brought the pipe about 2 inches closer to the wheel. So we had no choice but to take the new tank off and replace it with the old leaky tank. We then took the new tank to a local garage who said they could fix it for us. This was done with the handle of a sledge hammer. Now all we have to do is flush it to get rid of any lingering petrol fumes, have the solder repaired, and refit it. Simple. Whenever anybody heard we wanted to replace the fuel tank, the stock response was "Simple, that'll only take you an hour so". Two and half weeks and still going.
