Abstract

A fuel delivery assembly in an engine is provided herein. The fuel delivery assembly includes a surge pot including a housing with an inner wall enclosing fuel during engine operation, a fuel pump submerged within the fuel, the fuel pump including an inlet receiving fuel from the surge pot, and a fuel filter receiving fuel from an outlet of the fuel pump and positioned external to the inner wall.

Claims

1. A fuel delivery assembly in an engine, comprising:

a surge pot including a housing with a wall enclosing fuel during engine operation;

a fuel pump submerged within the fuel, the fuel pump including an inlet receiving fuel from the surge pot; and

a fuel filter receiving fuel from an outlet of the fuel pump and positioned external to the wall.

2. The fuel delivery assembly of claim 1, wherein the fuel filter has a cylindrical shape.

3. The fuel delivery assembly of claim 2, wherein the fuel filter is formed as a hollow cylinder with an annular shape in a horizontal cross-section.

4. The fuel delivery assembly of claim 1, wherein the fuel filter circumferentially surrounds the wall of the surge pot.

5. The fuel delivery assembly of claim 1, wherein the fuel filter is integrated into the surge pot.

6. The fuel delivery assembly of claim 1, wherein the fuel filter is releasably connected to the surge pot.

7. The fuel delivery assembly of claim 1, wherein the surge pot has a filter enclosure in which filter material of the fuel filter is received, a boundary of the filter enclosure defined by the wall and an outer wall of the surge pot.

8. The fuel delivery assembly of claim 1, further comprising a releasable fuel line coupling releasably coupled to the fuel filter and a fuel line extending between an outlet of a fuel pump and the fuel filter, the fuel pump arranged in the surge pot.

9. The fuel delivery assembly of claim 8, further comprising a second releasable fuel line coupling attached to an outlet of the fuel filter, the second releasable fuel line coupling attached to a second fuel line providing fuel to downstream engine components.

10. A fuel delivery assembly in a fuel delivery system of an engine, comprising:

a surge pot including a housing with an inner wall enclosing fuel during engine operation;

a fuel pump circumferentially enclosed by the inner wall, the fuel pump including an inlet receiving fuel from the surge pot;

a fuel filter receiving fuel from an outlet of the fuel pump and positioned external to the inner wall; and

a fuel line extending from the outlet of the fuel pump to the fuel filter through the surge pot, the fuel line being fluidly separated from fuel in the surge pot.

11. The fuel delivery assembly of claim 10, where the fuel filter is positioned in a filter enclosure between an outer wall of the surge pot and the inner wall.

12. The fuel delivery assembly of claim 11, where the inner wall and the outer wall define a portion of a boundary of the filter enclosure.

13. The fuel delivery assembly of claim 12, further comprising a surge pot cover releasably attached to the surge pot, an interior surface of the surge pot cover defining a second portion of the boundary of the filter enclosure.

14. The fuel delivery assembly of claim 10, where the fuel line extends into the fuel tank.

15. The fuel delivery assembly of claim 10, where fuel flows in a circumferential direction through the fuel filter.

16. The fuel delivery assembly of claim 10, where the fuel filter has an annular shape in a horizontal cross-section.

17. The fuel delivery system of claim 10, where the surge pot is positioned within a fuel tank.

18. The fuel delivery system of claim 11, where the outer wall fluidly separates the fuel filter from the fuel tank.
