SuperDave,
I looked at your page for the weld in bungs. I am assuming the ones listed are all aluminum, correct ?? Good prices man. What I did for my tank was get a regular NPT to -10 and then turn off the NPT end on the lathe. I welded it from the inside for a cleaner look. The next one I build I will look you up.
Thanks.

396- I sent you a PM.
Yes they are. And the do not have a hex flange. I thought the round flange looked better and would be easier to weld. Also they have a small locating delio on the back side so they stay put when you start to weld on them.
