Bruce,
Never heard of this. Seal ring should not allow any gas to escape. How much
gas are we talking? Maybe the vent hole in the cap is weeping gas fumes that
are condensing?

This winter I replaced the old, dried out gas cap seal with a new seal I cut out of a sheet of Viton. The gas tank was full to slightly above the cylinder that extends down in the the tank from the filler area. Then I noticed, while working in the garage, that the tank was wet with a film of gasoline. The level of the gas was nowhere near the top of the filler cap. I eventually siphoned off enough gas to lower it below the cylinder inside the tank which seem to stop this. I think that capillary action is causing the gas to go up the sides of the cylinder and then up and over the filler lip. But I would have thought that my new seal would stop this. Anyone else seen this phenomena ? Bruce '72 Eldo |
