I have performed the above procedure, including installing a Renazco billet filler neck and an in-line one way valve to the scavenge fuel hose. My problem is that I am building pressure inside the tank (fuel vapors normal expansion).
I thought the one way valve would stop the denser fuel from escaping, while allowing some air to exit to accommodate fuel vapors and ,of course, allowing air to come in to fill tank as fuel is depleted. Do I need a different valve, or should I just vent the hose to atmosphere without any valve?

I would appreciate a comment from those that have performed this modification.

TIA,

John
