    Maybe you guys can help - after doing some work lifting one side up at a time, I notice a continuous drip of gas coming from somewhere around the right side of the engine, down onto the diff, when the engine was idling.

    I set the truck down to check it out and the leak stops - couldn't find where it was from. Drive it a bit, keep checking, nothing. Dry as a bone.

    So I guess it was some little quirk, who knows? The off-camber position... whatever. It's gone for about a week.

    Today I park at work - there it is again! I get back home, it's gone!!!

    I figure a leak is a leak: why does it come and go?

    Anybody have this happen? Any idea what to look for?

    well, if its carbed, i might guess the hardline coming out of the frame is cracked, corroded or chafed thru... could be the rubber feed over to the pump, etc....

    the pump id mounted on the lower front passenger side on carbed moters.

    rubber lines run to it and a steel hard line runs to the carb.

    check that first.

    i just found on my friends truck that the PO had use a piece of rubber line to patch the steel line in his truck. no wonder it smelled like gas!

    how full of a tank did you have? this could have been gas coming out of the vent line for the tank. that would definetly cause an internitant problem

    Solved - thanks guys. It was the end of the rubber hose that attaches under the fuel pump. End had cracked, so I cut off an inch and put it back on. Why it was intermittent, I have no idea - maybe when it heated up?

    Anyways, another victory for the home mechanic! If I had taken in to a local shop who knows what they would have done!!
