If gassers don't need or use the pressure system then even on a two-line system, what do you use the second line for? Just a vent?
Sorry, I'm brand new to gas.

The second line lets air into the tank as the engine pulls out the gas. You do not want to create a vacume in tank. Just think more about it!!!!
