Abstract
A module constructed to be disposed within a fuel tank of the vehicle fuel system carries a vapor vent valve, a fuel pump and other components, such as a fuel lever sender and an overpressure relief valve and outlet. Each of these components may thus be inserted through a single opening into the fuel tank to reduce the number of openings in the fuel tank to thereby reduce the emissions of hazardous hydrocarbon fuel vapors from the fuel tank. Further, the module provides additional protection to the vapor vent valve to prevent sloshing fuel within the fuel tank from entering the vent valve and escaping from the fuel tank and being transferred to the fuel vapor storage canister. The module is constructed such that a portion containing the fuel pump is designed to break away from the rest of the module sealed to the fuel tank, the fuel pump will move away from the vapor vent valve during a vehicle accident instead of crashing into the valve and damaging or destroying it as in prior fuel tank assemblies.
