My "RTV" method of welding for the injector bungs. The trouble I had was the same problem I had the welding the rest of it, which was blowing through the thin metal. So I what I eventually did was dial the heat and feed way down and lay a bead on the thin metal, then went back over it with more power, effectively welding the weld to the bung, then stacked it, and then turned the heat up some more and stacked it again.... However I think I learned what setting would work well the next time I weld this thin metal.
CNCDude Scott made the injector bungs up and they are mint. They weld nicely and cut nicely as well.
I still have to do some finishing grinding/polishing on the inside of the ports, but then will give it a coat of fuel resistant sealant and then paint will make all the flaws go away
