AFT Axle Body Mounted Tank

REMOVAL

1. Drain the fuel into a container by siphoning through the fuel hose at the fuel pump-to-fuel tube connection.
2. Raise the rear of the vehicle.
3. Disconnect the ground cable on the vehicle battery to avoid electrical sparking at the tank. Then disconnect the fuel gauge sending unit wires at the fuel tank.
4. Loosen the clamps on the fuel filler hose and vent hose at the tank neck. Disconnect the hoses from the tank.
5. Remove the fuel line hairpin clips and disconnect the fuel lines from the fuel gauge sending unit.
6. Support the tank in position. Remove the nuts that attach the mounting straps to the "T" bolts.
NOTE: The "T" bolts are attached to body brackets located at the rear of the tank.
Disengage the straps from the J-bolts and the front body brackets. Lower the tank enough to gain access to the vapor valve.
7. Disconnect the vapor hose from the vapor control valve if the vehicle is equipped with carbon canisters.
8. Lower the fuel tank and remove it from underneath the vehicle.
9. If the fuel gauge sending unit is to be removed, turn the unit retaining ring counterclockwise and remove the sending unit retaining ring and gasket.
10. If the vapor control valve is to be removed, pull it out of the grommet located in the top of the tank and remove the grommet.

Typical Evaporative Fuel System Installation:

INSTALLATION

1. If the fuel gauge sending unit was removed, scrape away the old gasket material from the unit mounting surface on the fuel tank. Replace gasket, position the fuel gauge sending unit to the fuel tank and secure with the retaining ring.
2. If the vapor control valve was removed, install the grommet in the tank opening and press-fit the valve into place.
3. Attach the front ends of the mounting straps to the front body brackets.
4. Raise the tank high enough to connect the vapor hose to the vapor valve. Connect the hose.
5. Secure the strap ends to the T-bolts with the attaching nuts. Tighten nuts.
6. Connect the fuel line lines to the fuel gauge sending unit.
7. Connect the fuel filler hose and vent hose to the filler neck and vent neck at the tank. Tighten hose clamps.
8. Connect the vehicle battery ground cable. Connect the fuel gauge sending unit wires. Connect the fuel gauge sending unit wires.
