Matt, I remember you saying you bought a fuel tank sending unit for your American a year or so ago. Where did you get it? Is it holding up and working correctly. I have to add a fuel return line to my tank and was thinking of replacing the sender and adding a 3/8" pickup line at the same time and using the old 5/16 pickup as the return. I'd use the one in the car now, but it occasionally acts up and I'd like to start with a fresh one. Plus I need the O-ring! Thanks, Mark Price
