    The fitting where the line from the fuel pump meets the carb is leaking gas REALLY bad. I have tightened it snug, and it is still leaking the same. What should I do?... Its leaking on the manifold, and that cant be good..... :blush: What are my options? :confused: See pic below.

    I wouldn't trust teflon tape in a fuel application.

    Where is it leaking? Where the 2 fittings meet? Where the big fitting meets the carb? Or where the line goes into the fitting? Looks like the line is a little twisted and weird.

    The line itself is fine. And so is the small fitting. Its the big fitting.

    That fitting is pipe-threaded, which should be self sealing, it doesn't cost very much.

    Yep, easy to remove/replace, they also make repair nuts in case the threads are stripped.

    I see how the Large fitting would be easy to replace... but the fuel line is impossible to get out!

    gasket??

    You lose the little plastic gasket behind the big nut that screws into the carb??--without that it will leak no matter how tight it is... :confused: Those fine threads in the zinc carb strip real easy(and the carb can crack easy too,especially when forcing an "oversized" repair fitting into it..)--so be careful when tightening it..I'd refrain from running it until the leak is stopped--unless you have fire and theft on it,and dont like the vehicle..and dont mind walking home from a fire,IF you get out in time... :crazy:

    Looks like that line is pretty much near shot anyway. Remove the end at the fuel pump (or loosen as much as possible) then try and unthread it again. Seems to work for me, the nut can twist and the line can too, at least a little bit, which is enough to break the bond there.
