    Leaky Carb Input (74 fj40) [fixed {thanks poser!}]

    what i belive is the input fuel line is leaking at the attachment to the carb. It is the upper line on that little post deal of my carb. Any ideas as to what I should do first?

    Sounds to me like it is the return side of the fuel system...



    It is a banjo fitting, and unless the threads on yours are damaged, or somehow the fitting is cracked, it will not need to be replaced...are you sure it is leaking from the fitting, and not from the crush washers used to seal it, or possibly from someplace else?

    that fitting is spitting gas horribly out of the bottom of it (where the bottom of the fitting meets the top plate of the carb).

    Remove it and see if it is cracked, or if it is just the copper washer.....

    Thanks again Steve...the bolt (cener of fitting) was loose :rolleyes:! I can't belive i was stupid enough not to try that first. I did check the washers while i was at it an the ones at the top AND bottom looked good. Fitting (outer) looked good too. Tightended it down and fired it up...no more leaks

    The Internet is a great thing, but nothing will ever replace going out there, getting your hands dirty and figuring things out.
