I broke a fuel fitting (return line) leading to the filter on top of the engine. I patched it so that I could drive it home, the part is $380 and you can't just buy the fitting, its the whole line from engine to fuel tank. It was my fault, fitting was not coming off and it just snapped. Super tiny fitting, the ID is maybe 1/16". Parts guy said the part ships from national warehouse so hopefully its in stock and gets here soon.
My bush fix, this was on Christmas Eve day... nothing was open. Neighbor down the road builds tractors for tractor pulls, has a killer shop. Stopped by and told him what I needed (something to go from 3/8 down to 1/8 or smaller. He found these two fittings, threw them in the lathe, made them a press fit tolerance. Still added some solder to it. I safety wired everything to lessen the chances of it popping off. No leaks.
The fitting that broke... tiny little plastic fitting.
