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.

First claim

The invention claimed is:

1. 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;
where the fuel filter is positioned in a filter enclosure between an outer wall of the surge pot and the inner wall.

2. The fuel delivery assembly of claim 1 , where the inner wall and the outer wall define a portion of a boundary of the filter enclosure.

3. The fuel delivery assembly of claim 2 , 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.

4. The fuel delivery assembly of claim 1 , where the fuel line extends into a fuel tank.

5. The fuel delivery assembly of claim 1 , where fuel flows in a circumferential direction through the fuel filter.

6. The fuel delivery assembly of claim 1 , where the fuel filter has an annular shape in a horizontal cross-section.

7. The fuel delivery assembly of claim 1 , where the surge pot is positioned within a fuel tank.

8. The fuel delivery assembly of claim 1 , where the outer wall fluidly separates the fuel filter from a fuel tank.

9. The fuel delivery assembly of claim 1 , where the fuel filter circumferentially surrounds the inner wall of the surge pot.

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

11. The fuel delivery assembly of claim 1 , further comprising a first releasable fuel line coupling releasably coupled to the fuel filter and the fuel line.

12. The fuel delivery assembly of claim 11 , 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.
