### Removal Procedure

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.)

The fuel filter (2) is located under the rear of the car, behind the fuel tank. There is no service interval for fuel filter replacement. Replacement is required only if the fuel filter becomes restricted.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure .

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.
2. Raise the vehicle and suitably support.
3. Using back-up wrench to remove the fuel filter fitting.
4. Disconnect the quick -connect fitting at the inlet of the the in-pipe fuel filter. Refer to Plastic Collar Quick Connect Fitting Service .
5. Remove the fuel filter.
