A fuel delivery module (10) adaptable for use in a gasoline or diesel fuel tank includes certain common module components for use in both gasoline or diesel fuel delivery applications. The common module components include a support frame (12) having a first cover (14) for closing off an opening of the fuel tank and including a fuel supply port (20) and fuel return port (22) for communication to the engine fuel supply/return system and a second base cover for positioning on a bottom wall of the fuel tank and having a fuel pump-receiving chamber thereon. The base cover (30) includes a first diesel fuel pick-up opening (44) that can be communicated to the fuel supply port on the first cover by a suitable diesel fuel supply conduit when the fuel tank contains diesel fuel. The base cover also includes a second gasoline or diesel fuel opening (48) that is protected by a fuel pump filter (94) and is communicated to an inlet of a fuel pump (92) received in the fuel pump-receiving chamber (33) such that gasoline or diesel fuel is pumped to the fuel supply port on the first cover through a suitable fuel supply conduit. A diesel or gasoline fuel return conduit is connected to the return port on the first cover depending on the type of fuel contained in the fuel tank. The fuel supply conduits/connections and presence/absence of the fuel pump can be selected as required to adapt the fuel delivery module for use with a diesel or gasoline fuel tank.
Fuel delivery module adaptable for use in a gasoline or diesel fuel tank, comprising a support frame having a first cover for closing off an opening in an upper wall of the fuel tank, said first cover having a fuel supply port and fuel return port, and a second base cover for positioning on a bottom wall of said fuel tank and having a fuel pump-receiving chamber thereon, said base cover including a first fuel pick-up opening and a second fuel pick-up opening communicated to said fuel pick-up pump-receiving chamber, said fuel supply port being alternately communicated to said first fuel opening by a first fuel supply conduit or to a fuel pump received in said chamber by a second fuel supply conduit, said fuel return port being connectable to a fuel return conduit for returning fuel to said fuel tank.
A method of assembling a fuel delivery module for a fuel tank, comprising:
