Im looking into replacing my vent with a roll protection valve.I have a magnafuel 500 pump with a 10 an line and a 8an return line. into a 8 gallon cell. The vent tube now is 8 an, Will the rollover valve hurt the venting process of the cell. Do I need to go bigger to compensate? Thanks in advance

It will be fine.

Air is many times less dense than any liquid fuel, so a lot of it can flow through a relatively small orifice and quickly fill your cell.

Even with a vented cell is the filler cap supposed to be vented also or doesn't matter since the tank is vented?
