This procedure requires the use of tool J-46363, Fuel Line Release Tool, or equivalent.

Disconnect the negative battery cable.
Relieve the fuel system pressure.
Raise the vehicle.
Remove the fuel composition sensor bracket nuts and reposition it aside.
Clean all the fuel filter connections and the surrounding areas before disconnecting the fuel pipes in order to avoid possible contamination of the fuel system.
Using a flare nut wrench and backup wrench disconnect the fuel line fitting from the fuel filter.
Use the Fuel Line Release Tool, J46363, or equivalent to disconnect the quick connect fittings as follows: Pull the quick connect fitting back until the internal retainers hit the filter stop.

Twist one end of J-46363 and insert it between the fitting and the filter

Twist the opposite end of the tool and insert it between the fitting and filter

Once tool J-46363 is inserted, make sure it is parallel to the filter and fitting.

While holding the filter, push the fitting toward the filter in order to disconnect the quick connect fitting.

Remove the fitting from the filter. Remove the tool from the filter.

Slide the fuel filter from the bracket.
Inspect the fuel pipe O-rings for cuts, nicks, swelling, or distortion. Replace the O-rings if necessary.

To install: Slide a NEW fuel filter into the bracket.
While holding the filter, push the fitting towards the filter in order to connect the quick connect fitting.
Using a flare nut wrench and backup wrench connect the fuel line fitting to the fuel filter.
Position the fuel composition sensor/bracket into place and secure with the bracket nuts. Torque the nuts to 13 ft. Lbs. (17 Nm).
Lower the vehicle
