so for those who make their own fuel tanks, where are you getting your weld in bungs and caps for the filler necks? I've found a few online but they seem expensive for the application. I need something in steel, not aluminum. I don't want to go the backyard mechanic route and glue on some brass fittings or anything like that. I was hoping someone here had a cheap source for these parts, but maybe I just need to get over it and drop the dough for what I need.
