   in General Information.
2. Relieve fuel system pressure, refer to Fuel Pressure Relief Procedure .
3. Drain fuel tank, refer to Fuel Tank Replacement (4 Door Utility/Pickup) - Draining for the 4 Door Utility or Fuel Tank Replacement (2 Door Utility) - Draining for the 2 Door Utility.
4. Remove the fuel tank, refer to Fuel Tank Replacement (4 Door Utility/Pickup) or the Fuel Tank Replacement (2 Door Utility) .
5. Remove the fuel sender assembly, refer to Fuel Pressure Regulator Replacement .

•	Whenever the fuel tank is cleaned, the fuel pump strainer must be inspected. If the strainer is contaminated, replace the strainer and inspect the fuel pump.

•	Inspect the fuel pump inlet for dirt and debris. If found, replace the fuel pump.

6. Flush the fuel tank with hot water.
7. Pour the water out of the fuel sender assembly opening.
8. Rock tank to be sure that removal of water from tank is complete.

1. Inspect the in-line fuel filter for contamination.
2. Replace the filter if the filter is plugged.

Clean the fuel lines by applying air pressure in the opposite direction of the fuel flow.

Notice: Do not fold or twist the strainer when installing the sending unit. This action restricts fuel flow.

1. Install the new strainer (if necessary) on the fuel gage sending and pump unit.
2. Install the fuel gage sender and pump unit with a new seal into the fuel tank
3. Install the fuel tank. Refer to Fuel Tank Replacement (4 Door Utility/Pickup) or Fuel Tank Replacement (2 Door Utility) .
4. Disconnect the fuel feed line at the front of the vehicle.

10. Install the fuel line at the front of the vehicle.
11. Check all the connections, for leaks.
12. Tighten all the hose clamps.

1. Remove the fuel tank.
2. Drain the tank.
3. Plug all of the outlets.
4. Apply 7-10 kPa (1-1.5 psi) air pressure through the vent tube.
5. Test for leaks with a soap solution or by submersion.
6. Replace the tank if a leak is found.
