I don't know what Dax will suggest in the morning but I'm pretty sure that you can purge fuel tanks with nitrogen or something like that to allow them to be welded immediately.
Might even be cheaper for Dax if you know anyone close to you as the courier to Harlow and back ain't going to be cheap! I know its £70 from central london to mine and that's only about 40 miles.
Hope you get it sorted in time for Friday - I need the mirror
