FAQ:

Q: What is the purpose of a vented gas cap?

A: Vented Gas Cap Function The vented gas cap is designed to vent small amounts of air into the car gas tank line. The vented gas cap has a one-way release valve that is pressure-activated. When the pressure reaches a certain point (defined by so many pounds per square inch) the valve opens by a very small amount, relieving some of the pressure.

Q: What is Class B gas vent?

A: It operates on natural air convection and is also known as the Type B vent. Type B vents are a standard design that most modern gas furnaces use. It draws air from within the house for combustion.

Q: Do I need to vent the gas tank?

A: Gas tanks require a vent-atmospheric pressure must be allowed to enter the tank to prevent creating a vacuum as fuel is removed from the tank. However there is a problem with gas tank vents. They work both ways: They let air in and they can also let gasoline vapor out.
