So I now know that i for sure cannot tig weld. I'm not a bad self taught mig welder but tig welding is a whole nother story...
I decided to weld the stainless thru hauls on instead because the 0 rings kept leaking and i wanted to never worry about dropping the tanks again.
Tank on the left is a massacred stainless tig weld. Said screw this and went and bought a roll of stainless wire for the mig. Mig weld on the right.
Wish i would've done it to begin with...but thought, how hard can it be?...
I then coated the welds with liquid metal compound then sprayed over it with Leak Seal.
Here's a few pics with the 1 1/2" transfer hose installed.
