I would advise extreme caution when testing, as even 5 psi over the area of a fuel tank is sufficient to kill if it lets go, and a bicycle pump, used carelessly, can go to about 100 psi, which will certainly rupture a fuel tank. The correct way to pressute test it is to (optionally, to spot the bubbles and locate leaks) immerse it in water, in a bin as suggested, or any suitable container, and pump it up gently with something like a drain tester, which uses a U tube manometer to measure pressure and a squeezy rubber bulb to generate the pressure, and check for leakage. A "head" of a foot or so of water (0.5 psi approx) is sufficient.

 

You can hire drain testers, or rig up the equivalent.

For aluminium, yes Tig is the way to go. but as it was stated that he was using steel, My preference would be for Oxy as it is easier.
 
But then, this describes me perfectly " (and is a bit outdated ) "

Or mature? There's a flip side to every coin ;)
