A fuel pump 10 is described. The fuel pump 10 comprises a housing 12 and a plunger 14 positioned within the housing 12. A bottom spring plate 16 is in contact with at least a part of the plunger 14. A first spring 18 is located between the housing 12 and the bottom spring plate 16, the first spring 18 adapted to be compressed when the plunger 14 compresses fuel within the fuel pump 10. A second spring 20 is coupled between the housing 12 and the bottom spring plate 16, the second spring 20 positioned within the first spring 18. Figure 1.
