Leaking fuel tank?

[Deluks]

Did try welding a 60 gallon tank once.
Steam cleaned all morning then positioned with concrete block between me and tank. It went bang even after all that steam cleaning never tried again.
Because it was off a 1938 6 x 6 MACK I could not get replacement off shelf so then had to make new one from sheet steel. If available I would not repair other than get me home fix which would likely be soap method.

A million miles from a mk3 Polo!

(if you've got any pics though I'm sure they'd be entertaining!)

Fill it with water before you weld it.
