More like oozing fuel out of the tank at the fuel return line entry. Before I replace the fuel line and the rubber grommet (fuel line is a bit hard, grommet seems fine), I wanted to ask for thoughts. It only oozes under high RPMS, motor runs great. It seems to me that there is high pressure building in the tank causing the fuel to ooze out. Is the fuel cap supposed to vent pressure during running? Is there another problem causing high pressure in the fuel tank? Or should I just replace the grommet?
