My son and I have bee working to get our Ford 5000 select-o-speed diesel up and running after it's being dormant for many years. We replaced the fuel tank shut off valve and when attempting to reconnect the fuel line I kinked it. Didn't seem cracked but I figured I'd replace it anyway. Upon further inspection the line itself appears to have been made from copper tubing (not magnetic and I'm sure not factory original) with the sleeve from a compression nut pressed on the end. It appears as if this was done in an attempt to simulate a bubble flare. I can't seem to find this fuel line anywhere, might not be searching it correctly. It's the line between the tank and priming pump. Any insight as to what exactly this type of flare is, where I can find the correct line or what I can use to make one would be appreciated. Thanks.
