Hi folks. I replaced the fuel tank in my 1993 corolla because I thought it was the source of my fuel leak. It wasn't, but it had some rust holes in the top so it was due anyway. I noticed that my fuel lines are very crusty and the return line has a pretty serious leak, about 1 drop every 4 - 5 seconds. I put some JB Kwik Steel on it but it doesn't stick well because of the rapid rate of leakage. I was thinking of just getting a compression fitting and a short piece of metal line since it is so close to where it goes into the rubber line. My question is, does anyone know what size the line is? The guy at autozone seemed to think that it was 5/16" but that seemed a little big. My other thought was to just cut the line right before the leak and put some rubber hose on it and run it right up to the top of the tank, but I don't have any way of flaring it so I am not sure if it would stay on or not. I do have fuel line clamps but I am not sure if they would hold.
