For fuel sending and return lines, would it be best just to weld some nuts into the tank and then I can thread in some type of fitting later?
Would any type of metal tube be a good pickup for the fuel sending line, or should I put the opening on the bottom of the tank to reduce pumping losses.
I'm using a carb, so I'll plug the return opening, but if I do switch to fuel injection would I want the return line to just dump into the top of the tank, or is another part better?
