One traditional method is to pipe car exhaust fumes into the tank to flush
out
anything combustible and to displace all the air so there's no oxygen.
Exhaust
gas, having been burnt once is pretty much inert so any remaining petrol
vapour
won't ignite anyway. You need to keep the exhaust running while you weld of
course.

Have you ever personally done this, Dave?

Nope, as I don't weld, or at least only in extremis. I've heard it mentioned a
number of times though by racing people having to do emergency repairs at the
trackside.
