In the early days of ownership of my Coupe, I noticed that the right hand tank did leak out of the vent. After careful observation of the situation, I noticed that if I tightened the cap fully to the stop, the vent opening was about 10 degrees right of center. The fuel would just stream out of it. Next time up, I made certain that the vent rib was exactly parallel with the centerline of the plane. Leaking stopped. It is my theory that if the vent opening is straight forward, the air impact creates a pressurization of the tank, thus stopping overflow. Could be wrong here, but it just seems that way.
