I built my tank from 3mm aluminium If I was going to build one out of stainless I'd only use 1.2 for a sheer weight factor 1.6 would be far to heavy once finished. If it is built correctly 1.2 would be strong enough. One problem with stainless is it buckles with heat twice as bad as black steel or aluminium... You may start off with a beautiful tank before you weld it and after you weld it you think do I really want to put that buckled thing in my beautiful car... Because it will move.. The secret when you build a tank is not to weld anywhere near the bottom of the tank.. build the tank so that all the bottom corners are folded up then you only have to weld up the corners and around the top.. put 2 or three baffles inside weld securely across the bottom this stops any flexing of the bottom of the tank put the top on last and plug weld the tops of the baffles. I Tried building and internal swirl pot.... sounds good but believe its much simpler to have an external one
