ABSTRACT:
A filler neck for mounting between a fueling port and a fuel tank provides fuel entry into the tank and venting of fuel vapor from the tank while being serviced from a fuel dispensing nozzle having vapor recovery means. The filler neck comprises a reinforced rubber filler hose having a bore diameter sufficient for receiving the nozzle while also providing a vent path for fuel vapor from the tank through a vent hose mounted inside the filler hose bore. The internally vented filler neck is adapted for crash-proof fuel tank assemblies and eliminates multiple connections necessary on externally vented tanks. A mandrel assembly is also disclosed for making the internally vented filler neck.
