Patent number: 7520293Abstract: A fuel storage system for a transportation or recreational vehicle has a fuel tank that carries a vapor assembly that seeks out vapor pockets and controllably removes fuel vapor from the tank without releasing hydrocarbons to the surrounding environment. Preferably, a vent manifold attaches to a flange that sealably covers an access hole of the tank. At least one flexible tentacle extends from the manifold in the tank to a respective vapor vent valve that floats upon the surface of fuel at a vapor dome. When freely floating, the vent valve is open thus communicates the vapor dome through the tentacle and preferably with a filtering carbon canister. As fuel surface levels change or the vehicle tilts, changing the vapor dome size or location in the tank, the floating vapor vent valve is free to move generally with the vapor dome and as permitted by the flexibility of the trailing tentacle.Type: GrantFiled: February 16, 2006Date of Patent: April 21, 2009Assignee: TI Group Automotive Systems, L.L.C.Inventors: Steven R.

Patent number: 7353807Abstract: A fuel system has a jet pump assembly that fills a fuel reservoir for providing a reliable source of fuel to an electric motor fuel pump located in a fuel tank for a combustion engine. The electric fuel pump preferably delivers fuel at a controlled pressure to a series of fuel injectors of the engine. A small portion of the fuel exiting the electric fuel pump is diverted to the jet pump assembly that aspirates fuel from the fuel tank and into the reservoir. A biased normally closed pressure responsive valve prevents fuel flow to the jet pump when the electric fuel pump is running under impaired conditions, thus providing all the fuel to the combustion engine typically during cold engine start conditions.Type: GrantFiled: March 27, 2006Date of Patent: April 8, 2008Assignee: TI Group Automotive Systems, L.L.C.Inventor: Paul J.
