Many thanks to all those who have replied. I have ordered a new Herald tank from Fitchetts. I reasoned that a repair, knowing my luck, would result in the tank springing a leak somewhere, probably around the awful drain area. The smaller tank will afford more boot space and there are plenty of filling stations on the way to the shows. I always carry a fuel can anyway. If anyone wants a sound Vitesse tank, give me a shout, its free if you want it, just pick it up. Cheers, Ray.
