Fuel tanks are cheap Norm. A long time ago I would buy battery leads from the wreckers for $2 and take them out of a Mini as the battery is in the boot so you could make a few leads out of one.
I've drilled the grub screws out before,if you can fit a pin punch in an allen head grub screw then hit it with a hammer first to shock it loose or hit a grub screw bolt with a hammer ,the oxy will also work.
