I do not want to steel the thread, but I am only speaking of the exit flow from the tank to the overflow. If I fill the main tank start the engine and pull the overflow tank fuel poors out the vent because the fuel level is not below the femtocell fuel line inside the tank. I think I need some type of fitting the glues or screws to the top of the tank effectively raising the vent line above the main tank.

I would love love to see what others have done or if there is a suggestion in the plans as I bought an ARF

Thanks scott
