12. To replace the fuel pressure regulator, proceed to step 16.
13. Disconnect the fuel pump electrical connector.
14. Disconnect the fuel pump flex pipe quick connect fitting.
15. Remove the fuel pump from the fuel sender assembly.
16. Disconnect the fuel pressure regulator quick-connect fitting.

18. If the fuel sender assembly is being replaced, proceed to step 19.
19. Remove the fuel level sensor retaining clip (2).
20. Remove the fuel level sensor (3).
21. Remove the fuel pressure sensor (1).

### Installation Procedure

1. Install the fuel pressure sensor (1).
2. Install the fuel level sensor (3).
3. Install the fuel level sensor retaining clip (2).
