the fuel line that goes into the top of the tank was in bad shape. it looked like somebody had spliced a piece of copper tube and wrapped the ends in rubber (no flared ends) ... possilby to fix a leak? I tried to follow that crusty and cracked hose and it seemed to go UP into that corner just under the driver's tail light and then did a U and back down and ducked into the frame rail..., does that sound right?
is that a fuel return from the engine? I want to replace the whole piece of hose. it's not easy to figure anything out under there as there is around an inch of hardened tar (some sort of old undercoating) and years of mud. does it NEED to go up and loop back down? I'm guessing it needs to be higher than the fuel filler?
maybe I'm not making sense after all those gasoline fumes. btw, inside of my tank looks to be in good shape, fuel filler neck is a bit rusty.
