Unless the engine is mounted upside-down, or your gauges measure bar instead of PSI, this is all I have left. . . . . "You might want to try an underwater bubble test looking for defects in the float bowl or very small leakage paths through the seated valve. Remember, with the engine running, a very small amount of leakage can be accomodated by the engine's demand for fuel. With the engine not running, any leakage will result in fuel slowly trickling out through an open sight glass." . . . .or the bowl vent.
Edit -- N and S is not registering.
