SERVICE PROCEDURE

NOTE:

The procedure in this bulletin will require placing your entire arm into the fuel tank. The fuel tank must be empty for this procedure.

1. Remove the fuel pump from the fuel tank.

^ Refer to Section FL in the Service Manual for fuel pump removal information.

^ CAUTION:

The fuel tank is required to be less than 7/8 full before removing the fuel pump in order to prevent fuel spillage from the fuel pump opening.

2. Cut / split the side of a piece of rubber tube (vacuum line) and place it on the edge of the fuel pump opening.

^ This will protect your hands and arms from the sharp edge of the fuel tank.

Before continuing with this procedure:

^ Make sure the fuel tank is empty.

110

^ Read through all of the steps and understand the procedure.

3. Hold the Cut Bracket (cover) so the open side of the cover is towards the passenger side of the vehicle.

NOTE:

There is very little room inside the tank to maneuver the cover. You should hold it in the installation direction as you put it into the tank.

4. While holding the cover, reach into the tank.

5. Maneuver the cover to the FLV valve and snap the cover onto the valve.
