Yes, the fuel tank or cell requires venting to the outside of the vehicle. Do not use a vented gas cap in lieu of a true tank or cell vent

Very true. Too small of a vent, especially for an engine that can consume a LOT of fuel quickly can result in either the pump "stalling" out and cavitating from vacuum in the tank or you can actually start collapsing the tank!
