A friend is having a fuel problem. Engine runs fine for 10 minutes, then quits. After repriming the fuel system, it's good for another 10 minutes. Removing the tank filler cap doesn't change things. Engine runs fine off an outboard tank.
To me, it sounds like an air leak into the fuel line up above the level of the fuel in the tank. Perhaps an air leak at the tank shutoff valve or one of the threaded or barb connections. Or perhaps a crack/pinhole in the fuel tube inside the tank.
I'd like to put a little air pressure into the line, soap the connections, and look for bubbles. Any suggestions for the best way to do this? I don't want to just hook it up to the air compressor. Perhaps run the compressor output through a propane regulator?
Oh yeah - does the diagnosis sound reasonable? Anything I might have missed?
