Ok, my 48 is geting a efi magnum swap. I'm in question as to were would be a good place to tap into fuel tank to put a barbed fitting for the 5/16 hose. I was thinking about drilling a hole in the filler tube and thread the fitting in, then seal it up. I know i should drop the tank and weld a bung in it, but i dont want to do that if i dont have to. Any ideas from any one would be appretiated
