Fuel delivery module for low-profile fuel tank
A fuel delivery module for a vehicle having a fuel tank. The fuel delivery module comprises a flange, a reservoir, a fuel pump, a guide rod, a guide rod receiver, and an elastically deformable member. The flange couples to an opening of the fuel tank. The reservoir is in fluid communication with the flange and a fuel pump connected to the reservoir transports fuel from inside the fuel tank to outside the fuel tank through the flange. The guide rod is coupled to the flange at a first end of the guide rod and the guide rod receiver is fixedly disposed on the reservoir. The elastically deformable member is moveably coupled to the guide rod and to the reservoir such that a second end of the guide rod is selectively receivable in the guide rod receiver.

2. The fuel delivery module of claim 1 , wherein the elastically deformable member is configured to move the fuel delivery module between an operating position in which the guide rod is received in the guide rod receiver, and an insertion position in which the guide rod is not received in the guide rod receiver.
3. The fuel delivery module of claim 2 , wherein the guide rod receiver is positioned and oriented to be substantially co-axial to the guide rod when the reservoir is substantially horizontal and the fuel delivery module is in the operating position.
4. The fuel delivery module of claim 2 , further comprising a spring disposed to urge the reservoir toward a bottom surface of the fuel tank when the fuel delivery module is in the operating position.
5. The fuel delivery module of claim 4 , wherein the spring urges the reservoir to be seated at the bottom surface of the fuel tank and to secure the reservoir in the operating position when the guide rod is received in the guide rod receiver.
6. The fuel delivery module of claim 5 , wherein the reservoir comprises a bottom surface, and wherein the spring and the bottom surface cooperate to restrict movement of the reservoir relative to the flange along the vertical axis.
7. The fuel delivery module of claim 1 , wherein the guide rod and the guide rod receiver cooperate to restrict movement of the reservoir relative to the flange in the horizontal plane.
8. The fuel delivery module of claim 1 , wherein the guide rod receiver comprises a conical region defining a draft angle for facilitating insertion of the guide rod into the guide rod receiver.
9. The fuel delivery module of claim 1 , wherein:
the guide rod comprises a pair of guide rods each coupled to the flange at a first end of the guide rod;
the guide rod receiver comprises a pair of a guide rod receivers fixedly disposed on the reservoir; and
the elastically deformable member is moveably coupled to the pair of guide rods and to the reservoir, such that a second end of each of the guide rods is selectively receivable in one of the pair of guide rod receivers.
10. The fuel delivery module of claim 1 , further comprising a jet pump provided in the reservoir to create a venturi effect to draw fuel from the fuel tank into an interior volume of the reservoir.
11. The fuel delivery module of claim 10 , further comprising, in the reservoir, a pressure regulator and a fuel filter for controlling the fuel delivered by the fuel pump to the flange.
12. The fuel delivery module of claim 1 , wherein the elastically deformable member comprises a metal strip for providing a rotation movement of the reservoir relative to the guide rod.
13. The fuel delivery module of claim 1 , wherein the fuel pump is disposed in the reservoir, and further comprising a fuel line connecting the fuel pump to the flange to deliver fuel from the interior volume of the reservoir to the flange.
14. The fuel delivery module of claim 12 , wherein the elastically deformable member further comprises a sliding member to connect the metal strip to the guide rod, and wherein the sliding member provides a sliding movement of the reservoir relative to the guide rod.
15. The fuel delivery module of claim 12 , further comprising a ring stopper disposed on the guide rod to cooperate with the sliding member to define a limit of linear movement for the reservoir relative to the guide rod.
16. The fuel delivery module of claim 1 , wherein the elastically deformable member comprises a metal string.
17. The fuel delivery module of claim 1 , further comprising a handle to manipulate the linear movement of the reservoir relative to the guide rod and the flange.
18. A fuel delivery module for a vehicle having a low profile fuel tank, the fuel delivery module comprising:
a flange for coupling to an opening of the low profile fuel tank;
a reservoir in fluid communication with the flange to transport fuel from inside the fuel tank to outside the low profile fuel tank through the flange, the reservoir comprising a bottom surface;
a connecting member for connecting the flange to the reservoir, the connecting member including a guide rod and an elastically deformable member having a first end moveably coupled to the guide rod and a second end fixedly attached to the reservoir, to facilitate movement of the fuel delivery module between an insertion position in which the reservoir is movably coupled to the flange to permit installation of the fuel delivery module in the low profile fuel tank, and an operating position in which the reservoir is fixedly coupled to the flange to securely seat the fuel delivery module in the low profile fuel tank.
19. The fuel delivery module of claim 18 wherein the elastically deformable member is shaped and constructed to permit variable orientation of the reservoir relative to the flange in the insertion position.
20. A two-position connecting member for connecting a flange of a fuel delivery module to a reservoir of the fuel delivery module, the connecting member comprising:
a guide rod coupled to the flange at a first end of the guide rod;
a guide rod receiver fixedly disposed on the reservoir; and,
an elastically deformable member having a first end moveably coupled to the guide rod and a second end fixedly attached to the reservoir, such that a second end of the guide rod is selectively receivable in the guide rod receiver so as to facilitate movement of the fuel delivery module between an insertion position in which the reservoir is movably coupled to the flange, and an operating position in which the reservoir is fixedly coupled to the flange.
