My boat since day 1 has been plagued with overflow issues from the check valve. The check valve is a one way valve that lets the gas tank "Vent" but not suck in water. The problem is the vent sits atop the gas tank and the vent hole on the side of the boat is either at the same height or lower then the vent on the tank. I installed a plastic check valve a while back but it didn't seem to do much. I still have gas spewing out the side of my boat when I have a full tank and go around a right hand corner.
I'm asking for some advice on the proper way that a check valve system should be run or installed. I'm tired of having gas run down the side of the boat and eat away my decals ect.
Thanks in Advance
