Removal Procedure
- Ensure that fuel level in the tank is less than 1/4 full. If necessary, drain the fuel tank to at least this level. Refer to Fuel Tank Draining .
- Position the vehicle on the hoist.
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
- Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
- Raise the vehicle to a comfortable working position.
- Remove the exhaust system intermediate pipe with the muffler.
- Remove the rear heat shield retaining bolts.
- Remove the fuel filler pipe lower bracket attachment screw.
- Disconnect the EVAP canister vent hose.
- Loosen the fuel filler pipe hose clamp closest to the fuel tank.
- Disconnect the quick connect at the recirculation line.
- Disengage the filler pipe hose from the fuel tank.
- Remove the tank grounding strap attachment nut located near the fuel filter.
- Remove the fuel tank strap bracket and fuel line stone chip guard, protecting the fuel line connections between the fuel tank and the chassis fuel bundle.
- Disconnect the fuel feed line after the fuel filter.
- Disconnect the fuel return and the EVAP canister purge lines between the tank and the chassis fuel bundle.
- Disconnect the fuel tank electrical connections.
- Loosen the front tank strap bolts, but do not remove.
- With the aid of an assistant, remove the 2 rear tank retaining strap bolts.
Caution: Do not allow smoking or the use of open flames in the area where work on the fuel or EVAP system is taking place. Anytime work is being done on the fuel system, disconnect the negative battery cable, except for those tests where battery voltage is required.
Caution: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.
Caution: Fuel supply lines will remain pressurized for long periods of time after the engine is shutdown. This pressure must be relieved before servicing the fuel system.
Caution: Whenever fuel lines are removed, catch fuel in an approved container. Container opening must be a minimum of 300 mm (12 in) diameter to adequately catch the fluid.
Important: If there is more than 11.4 liters (3 gallons) of fuel in the tank, insert a suitable siphon hose into the tank filler neck and remove the remaining fuel into a certified fuel handling cart.
Caution: Whenever fuel line fittings are loosened or removed, wrap a shop cloth around the fitting and have an approved container available to collect any fuel.

Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the fuel tank mounting strap to 20 N·m
(15 lb ft).
Notice: Replace plastic fuel line retainers whenever the fuel supply or return line is disconnected at the fuel rail. Install the new retainer into the female cavity of the connection. Care must be taken to ensure that the locking tab is centered in the window of the female cavity. Firmly press the female connection onto the male end until a click is heard, then pull back to confirm engagement. Pinched, kinked, or damaged fuel lines must be replaced.
Important: Lubricate the male ends of the filter with clean engine oil to ease installation.
Tighten
Tighten the fuel tank grounding strap attachment
to 4.5 N·m (35 lb in).
Important: Ensure that the EVAP vent solenoid pipe is installed in position on the filler pipe bracket.
Important: Ensure that the fuel pipe connecting hose is installed until it touches the fuel tank body. The hose clamp should be located within 6 mm (1/4 in) of the end of the connector hose.
Tighten
Tighten the fuel fill neck-to-fuel tank clamp to
5 N·m (44 lb in).
Tighten
Tighten the fuel fill pipe-to-body (lower) to 13 N·m
(9.5 lb ft).
Tighten
Tighten the rear heat shield to 8 N·m
(71 lb in).
Tighten
Tighten the fuel line stone chip guard to 12 N·m
(106 lb in).
Tighten
Tighten the battery terminal bolts to 17 N·m
(13 lb ft).
