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.

[ What is claimed is:] [1.]1. A module adapted to be carried by a fuel tank, comprising:a housing constructed to be at least partially received in an opening of a fuel tank and having a lower portion and an upper portion with a flange constructed to be sealed to a wall of the fuel tank in assembly, a first fluid outlet constructed to communicate the interior of the fuel tank with the exterior of the fuel tank,a fuel pump in the tank, carried by the lower portion of the housing and having an inlet in the tank through which fuel is drawn from the tank and an outlet through which fuel is discharged under pressure with the outlet of the fuel pump communicating with the first fluid outlet to discharge fuel through the first fluid outlet to the exterior of the tank; andat least one frangible arm interconnecting the upper portion and lower portion of the housing and constructed to break when a force greater than a threshold force acts on the arm to permit the lower portion to separate from the upper portion of the housing without destroying the seal between the flange and the wall of the tank.
