Mod_auger, leak can be a royal pain in the rear. Although this isn't going to solve "your" problem, thought it might be worth mentioning for leaks in general. When the vent starts to leak on the gas cap, I made new gaskets by taking a small sheet of gasket material and punching .22 holes in the material followed by a .38 punch (or thereabouts) So now I have a small gasket to install on the vent screw on top of the cap. Engine shop showed me this trick instead of replacing the small little rubber gasket that always gets "bunged" up. Made several and put them in my small lure carrier I bring ice fishing. I'm using the sizes above as a guideline, when I made them up I used empty shell casings off my reloading bench. Whatever was handy and seemed to work at the time.
Good luck with the gas line leak....Augers are so expensive nowadays it's worth taking a few minutes to keep them up to speed.
