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.
A method of venting gases from a fuel tank at the time fuel is introduced into the fuel tank and when the fuel is not introduced into the fuel tank, comprising, at the time the fuel is introduced into the fuel tank, collecting the gases inside the fuel tank into a breathing system, including a fill vent tube placed substantially inside the fuel tank and a first exit line, the fill vent tube connected to a first end of the first exit line and, at the time the fuel is not introduced into the fuel tank, collecting the gases inside the fuel tank into a venting system, including a venting tube and a second exit line, place substantially inside the fuel tank, the venting tube connected to a first end of the second exit line, and conducting the gases outside of the fuel tank through a second end of the first exit line and a second end of the second exit line, the fill vent tube and the venting tube egressing the fuel tank through a single opening in the fuel tank.
