In-Line Fuel Filter Replacement. Chevrolet Corsica 1996

For 1990-2009 cars

### Removal Procedure

The fuel filter is located under the rear of the car, rearward of the fuel tank. There is no service interval for fuel filter replacement. Replacement is required only if the fuel filter becomes restricted.

1. Disconnect the negative battery cable.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure .
3. Raise the vehicle and suitably support.

Caution: Provide additional support when a vehicle is on a hoist in the following ways:

• | Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.

• | Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
4. Use a back-up wrench in order to remove the fuel filter fitting.

Caution: In order to Reduce the Risk of Fire and Personal Injury:

• | If nylon fuel pipes are nicked, scratched or damaged during installation, Do Not attempt to repair the sections of the nylon fuel pipes. Replace them.

• | When installing new fuel pipes, Do Not hammer directly on the fuel harness body clips as it may damage the nylon pipes resulting in a possible fuel leak.

• | Always cover nylon vapor pipes with a wet towel before using a torch near them. Also, never expose the vehicle to temperatures higher than 115°C (239°F) for more than one hour, or more than 90°C (194°F) for any extended period.

• | Before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the male pipe ends. This will ensure proper reconnection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.)

Caution: Wear safety glasses when using compressed air in order to prevent eye injury.

5. Grasp the filter and the nylon fuel connection line fitting. Twist the quick-connect fitting 1/4 turn in each direction to loosen any dirt within the fitting. Use compressed air in order to blow out dirt from the quick-connect fittings at the end of the fuel filter.
6. Remove the quick connect fitting by pushing inward toward the filter. Grasp the plastic tab around the connector and pull the connector apart.
7. Remove the fuel filter (1).

### Installation Procedure

Caution: Always apply a few drops of clean engine oil to the male pipe ends before connecting the fuel pipe fittings in order to reduce the risk of fire and personal injury. This will ensure proper reconnection and prevent a possible fuel leak. During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.

1. Remove the protective caps from the new filter.
2. Install the filter in the same position as the old filter.

• | Apply a few drops of clean engine oil to the male tube end of the filter and of the fuel sender assembly.

• | Push the connectors together in order to cause the retaining tabs/fingers to snap into place.

• | Once installed, pull on both ends of each connection in order to make sure they are secure.

Tighten

• | Use a back up wrench to prevent filter, O-ring or fuel line damage.

• | Tighten the fitting to 27 N·m (20 lb ft).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the fuel filter fitting using a new O-ring.
4. Lower the vehicle.
5. Install the fuel filler cap.
6. Connect the negative battery cable.
7. Inspect for fuel leaks through the following steps:

7.1. | Turn the ignition to the ON position for two seconds.

7.2. | Turn the ignition to the OFF position for ten seconds.

7.3. | Turn the ignition to the ON position.

7.4. | Check for fuel leaks.
