I have an RCI fuel cell and apparently the roll over vent only works if you completely roll over because when I'm on an incline my fuel just dumps out through that vent. So I thought I would just slap on a check valve, but I noticed that most of them need at least 2 to 3 psi to open. Is there enough vacuum in the tank to do this? And the other question is does it need to be rated for fluid use or will air be fine?
