Pump spacer/dampening structure for fuel delivery system

1. A fuel delivery system comprising:

a filter for filtering fuel, the filter having an internal wall defining a pocket,

a fuel pump in the pocket for pumping filtered fuel to an engine,

a pump spacer structure surrounding at least a portion of the fuel pump and positioning the fuel pump within the pocket, the pump spacer structure having a portion engaging the internal wall of the filter, and

dampening structure, between the pump spacer structure and the fuel pump, constructed and arranged to dampen vibration generated by the fuel pump,

wherein the pump spacer structure defines capturing structure to capture the dampening structure so as to remain between the fuel pump and the pump spacer structure, and

wherein the capturing structure is a generally U-shaped flange and a bottom of the flange is constructed and arranged to engage a portion of the fuel pump to control an insertion depth of the fuel pump into the pocket.

2. The system of claim 1 , wherein the dampening structure is an elastomer member.

3. A fuel delivery system comprising:

a filter for filtering fuel, the filter having an internal wall defining a pocket,

a fuel pump in the pocket for pumping filtered fuel to an engine,

a pump spacer structure surrounding at least a portion of the fuel pump and positioning the fuel pump within the pocket, the pump spacer structure having a portion engaging the internal wall of the filter, and

dampening structure, between the pump spacer structure and the fuel pump, constructed and arranged to dampen vibration generated by the fuel pump,

wherein the capturing structure is a generally U-shaped flange and wherein the dampening structure is an elastomer member, and

wherein the elastomer member is an O-ring.

4. A fuel delivery system comprising:

a filter for filtering fuel, the filter having an internal wall defining a pocket,

a fuel pump in the pocket for pumping filtered fuel to an engine,

a pump spacer structure surrounding at least a portion of the fuel pump and positioning the fuel pump within the pocket, the pump spacer structure having a portion engaging the internal wall of the filter, and

dampening structure, between the pump spacer structure and the fuel pump, constructed and arranged to dampen vibration generated by the fuel pump,

wherein the pump spacer structure defines capturing structure to capture the dampening structure so as to remain between the fuel pump and the pump spacer structure, and

wherein a flange is associated with the filter at an end of the filter, the pump spacer structure includes a wall extending from the capturing structure to contact an underside of the flange so as to position the dampening structure with respect to the fuel pump.

5. The system of claim 4 , wherein the pump spacer structure is of plastic material and the dampening structure is an elastomer member.

6. A fuel delivery system comprising:

a filter for filtering fuel, the filter having an internal wall defining a pocket,

a fuel pump in the pocket for pumping filtered fuel to an engine,

a pump spacer structure surrounding at least a portion of the fuel pump and positioning the fuel pump within the pocket, the pump spacer structure having a portion engaging the internal wall of the filter, and

means, between the pump spacer structure and the fuel pump, for dampening vibration generated by the fuel pump,

wherein the pump spacer structure defines capturing structure to capture the means for dampening so as to remain between the fuel pump and the pump spacer structure and wherein the capturing structure is a generally U-shaped flange, and

wherein a bottom of the flange is constructed and arranged to engage a portion of the fuel pump to control an insertion depth of the fuel pump into the pocket.

7. The system of claim 6 , wherein the means for dampening is an elastomer member.

8. A fuel delivery system comprising:

a filter for filtering fuel, the filter having an internal wall defining a pocket;

a fuel pump in the pocket for pumping filtered fuel to an engine,

a pump spacer structure surrounding at least a portion of the fuel pump and positioning the fuel pump within the pocket, the pump spacer structure having a portion engaging the internal wall of the filter, and

means, between the pump spacer structure and the fuel pump, for dampening vibration generated by the fuel pump,

wherein the pump spacer structure defines capturing structure to capture the means for dampening so as to remain between the fuel pump and the pump spacer structure, and

wherein a flange is associated with the filter at an end of the filter, the pump spacer structure includes a wall extending from the capturing structure to contact an underside of the flange so as to position the means for dampening with respect to the fuel pump.

9. The system of claim 8 , wherein the pump spacer structure is of plastic material and the means for dampening is an elastomer member.

10. A method of positioning a fuel pump with respect to a filter and dampening vibration of the fuel pump, the method including:

providing a filter for filtering fuel, the filter having an internal wall defining a pocket,

placing a fuel pump in the pocket for pumping filtered fuel to an engine,

surrounding at least a portion of the fuel pump with a pump spacer structure thereby positioning the fuel pump within the pocket, and

providing a dampening structure between the pump spacer structure and the fuel pump to dampen vibration generated by the fuel pump,

wherein the step of providing a dampening structure includes providing an O-ring.

11. The method of claim 10 , wherein the pump spacer structure defines a channel therein, the method including passing a wire through the channel.
