Trouble filling H3 gas tank.

[Camou2]

There is a flaper valve in the fill pipe close to the top of tank to keep fuel from sloshing out. This valve can get stuck and will cause the problem you are having during filling up. You can jamb a broom stick or other appropriate tool down the filler nozzle to open it up. Don't know a permanent solution except to have the dealer replace the fill pipe and/or complete tank system.
