Abstract
An internal gas removal system for a fuel tank is comprised of a venting system and a breathing system, both of which are placed substantially completely inside the fuel tank. The breathing system removes gases from the fuel tank while fuel is introduced into the fuel tank, while the venting system removes gases from the fuel tank while the vehicle is operated and the fuel is not introduced into the fuel tank. Both, the venting and the breathing systems are connected to their respective exit lines which exit the fuel tank through a single dedicated opening or through a filler pipe. A method of making the internal gas removal system comprises introducing the breathing and the venting systems into a blow mold and subsequently blow-molding the fuel tank around these systems.
