Personal injury or death can result from a fire. Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. Clean up all leaked or spilled fuel. Do not smoke while working on the fuel system. Turn the disconnect switch OFF or disconnect the battery when changing fuel filters.

In order to keep the engine in optimum condition, it is important to keep the fuel free from contamination. As fuel system contamination usually occurs during refueling, the following points should be observed:

• Only use clean fuel of the correct grade from a reliable source.

• Do not refuel from contaminated containers or containers that are not suitable for fuel storage.

• Do not use contaminated equipment.

• Regularly clean the outside of the fuel filler cap and the area around the fuel filler cap.

• Only use Caterpillar approved fuel filters. The use of Caterpillar filters is essential in order to protect the fuel system.

• Do not service the fuel filters ahead of the suggested maintenance interval, unless you are instructed by the monitoring system. This will increase the risk of contamination in the fuel system.

Note: In order to reduce the risk of contamination in the system, do not remove the primary fuel filter and the secondary fuel filters simultaneously. Perform these operations separately.

Note: After the engine has stopped, you must wait for 60 seconds in order to allow the fuel pressure to be purged from the high-pressure fuel lines before any service or repair is performed on the engine fuel lines.

1. Open the engine compartment. The fuel filter element is located on the right side of the machine toward the rear of the engine compartment.

2. Turn the fuel supply valve (if equipped) to the OFF position before performing this maintenance.

3. Place a suitable container under the water separator in order to catch any fuel that might spill. Clean up any spilled fuel. Clean the outside of the water separator and the fuel filter.

    Note: Do not fill the fuel filter before you install the fuel filter.

    1. Install a new filter hand tight until the seal of the filter contacts the base. Note the position of the index marks on the filter in relation to a fixed point on the filter base.

       Note: There are rotation index marks on the filter that are spaced 90 degrees or 1/4 of a turn away from each other. When you tighten the filter, use the rotation index marks as a guide.

    2. Tighten the filter according to the instructions that are printed on the filter. Use the index marks as a guide.

11. Install the clear bowl on the filter. Ensure that the sensor (if equipped) is in the correct position.

12. If equipped, install the wiring harness to the sensor.

13. Be sure to dispose of the fuel in a safe place.
