Thanks for visiting Just Answer,
You need to drop the fuel tank to change the pump..
Disconnect the negative battery cable.
Relieve the fuel system pressure. (You can also remove the cap and wait a couple hours before replacing the pump) Refer to Fuel Pressure Release Procedure .TOOLS REQUIRED
* J 34730 Fuel Pressure Gauge
WARNING: Relieve the fuel system pressure before servicing fuel system components In order to reduce the risk of fire and personal Injury. After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the chance of personal Injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may leak out. Place the towel In an approved container when the disconnection Is complete .
Loosen the fuel filler cap in order to relieve the tank vapor pressure.
Connect the gauge J 34730-1A or the equivalent to the fuel pressure connection.
Wrap a shop towel around the fitting while connecting the gauge in order to avoid spillage.
Install the bleed hose into an approved container and open valve in order to bleed the system pressure. The fuel connections are now safe for servicing.
Drain any fuel remaining in gauge into an approved container. Use a hand operated pump device in order to remove the fuel through the filler neck. NOTE : If pump is equipped, make sure to hook up the static ground wire to a metal part of gas tank before you begin.
4. Remove the fuel tank and sender assembly. Notes
Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby .
- Disconnect the negative battery cable.
- Use a hand operated pump device in order to remove the fuel through the filler neck. NOTE : If pump is equipped, make sure to hook up the static ground wire to a metal part of gas tank before you begin.
- Raise the vehicle.
- Loosen the filler neck hose clamp at the fuel tank.
- Disconnect the fuel tank filler neck from the fuel tank.
- Support the fuel tank.
- Remove the fuel tank shield.
- Remove the tank straps.
Notice: Care must be used to ensure that the connections to both roll over valves are disconnected prior to lowering the fuel tank more than 51 mm (2 in). Roll over valves are located at both the front and rear of the fuel tank.
Notice: Extreme care must be used when lowering the fuel tank. The fuel sender is made of plastic and may be damaged when lowering the fuel tank.
- Lower the fuel tank.
- Disconnect the fuel and vapor hoses and the electrical connections at the sender.
- Remove the fuel sender and seal ring, using the tool J36608.
- Discard the old seal ring.
- Purge tank, if being repaired.
- Install a new seal ring.
Notice: Do not fold or twist the strainer when installing the sending unit. This action restricts fuel flow.
- Reinstall sender using tool J36608.
- Raise tank slightly.
- Reconnect the fuel and vapor hoses and the electrical connections at the sender.
- Ensure the ground strap is also reinstalled to the body.
- Raise the tank fully.
- Reinstall the fuel tank filler neck to the tank.
- Tighten the clamp.
Notice: The strap nuts must be tightened by steps, alternating between the four nuts until the specified torque is reached. Otherwise, the bottom of the tank will flex upward and the fuel gage will indicate fuel remaining in the tank when the tank runs dry.
- Install the fuel tank brackets with insulator strips in place.
- Tighten the strap nuts to 45 Nm (33 lb. ft) .
- Install the fuel tank shield
- Lower the vehicle.
- Replenish fuel.
- Reinstall fuel tank filler cap.
- Reconnect the negative battery cable.
- If a memory retention device was not used, please reset (to the extent possible) all devices that lost their memory after the battery was disconnected.
- Check for leaks.
1. Install a new seal, sending assembly and lock ring. Make sure the lock ring alignment holes fit over the tabs on the tank.
2. Install the cam lock assembly. Turn the cam lock clockwise to lock it.
3. Install the fuel tank. Refer to Fuel Tank Assembly .
4. Add fuel removed from the tank.
5. Connect the negative battery cable.
6. Check for fuel leaks.
6.1. Turn the ignition ON for 2 seconds.
6.2. Turn OFF the ignition for 10 seconds.
6.3. Again, turn the ignition switch to the ON position.
6.4. Check for fuel leaks.
