REMOVAL & INSTALLATION
(see
Figures 1 and 2)
CAUTION
The fuel injection system remains under pressure, even after the
engine has been turned
OFF. The fuel system pressure must be relieved before
disconnecting any fuel lines. Failure to do so may result in fire and/or
personal injury.
-
Relieve the fuel system pressure using the recommended procedure.
-
Disconnect the negative battery cable.
-
Drain the fuel tank, then remove the fuel tank from the vehicle.
-
While holding the modular fuel sender assembly down, remove the
snap-ring from the designated slots located on the retainer.
WARNING
The modular fuel sender assembly may spring up from its position.
When removing the modular fuel sender from the tank, be aware that the
reservoir bucket is full of fuel. It must be tipped slightly during
removal to avoid damage to the float.
-
Remove the external fuel strainer.
-
Detach the Connector Position Assurance (CPA) piece from the
electrical connector and detach the fuel pump electrical connector.
-
Gently release the tabs on the sides of the fuel sender at the
cover assembly. Begin by squeezing the sides of the reservoir and
releasing the tab opposite the fuel level sensor. Move clockwise to
release the second and third tabs in the same manner.
-
Lift the cover assembly out far enough to detach the fuel pump
electrical connection.
-
Rotate the fuel pump baffle counterclockwise and remove the baffle
and pump assembly from the retainer.
-
Slide the fuel pump outlet out of slot, then remove the fuel pump
outlet seal.
To install:
-
Install the fuel pump outlet seal, then slide the fuel pump outlet
in the slots of reservoir cover.
-
Install the fuel pump and baffle assembly onto the reservoir
retainer and rotate clockwise until seated.
-
Install the lower retainer assembly partially into the reservoir.
Line up all 3 sleeve tabs. Press the retainer onto the reservoir making
sure all 3 tabs are firmly seated.
Gently pull on the fuel pump reservoir from retainer to assure a
secure fastening. If not secure, replace the entire fuel sender.
-
Attach the fuel pump connector.
-
Fasten the CPA connector to the fuel sender cover.
-
Install a new external fuel strainer.
-
Install the modular fuel sender.

Pressurize the fuel system and verify no leaks.
