what alloy the tank is. I also want to weld in two stainless outlet bungs.

I won't be doing any welding BTW, I will need to find a guy.

Right now I'm just worried about alloy compatibility.


I also have a Spectra tank that is said to be stainless (nice tank). I got a comp engineering (which isn't stainless) sump and my friend welded it on 3 years ago and it's been great so far. Not saying it's right or wrong. I did use a 3 stage etching/coating/sealer on the inside though.
