Re: GS 39 Fuel Tank Vent Line
I recently added fuel and initially had the old problem of the fuel backing up in the fill pipe. Then I noticed that there was a little fuel squirting out of the vent line at the transom (into a "capture-cup"). After that stopped, I didn't get any backup and could fuel at a normal rate. That gave me the clue that there had probably been some fuel sitting in the vent line. I had not been able to install the line in a continuous uphill run from the tank to the transom vent, allowing any fuel that gets in the line to run back into the tank.
