Ended up with just a generic fuel filter with 3/8 hose nipples on the ends. Had to drop the tank again and replace the sending unit because the metal return line was leaking. Fixed a bad connection on the starter and got it fired up and driving. I have a leak where the oil pressure sensor is, that will need fixed before I do any driving with it, and of course I should hook up the rest of the exhaust, but this is a very exciting moment. Better quality video is on the way. https://www.youtube.com/watch?v=p9vsqcLa74M
