TUBE ASSEM. (61 in. long) 1V6191 - Caterpillar

Personal injury can result from air pressure.Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing.Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.
Personal injury can result when using cleaner solvents.To help prevent personal injury, follow the instructions and warnings on the cleaner solvent container before using.
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.
Do not pre-fill the fuel filter with fuel before you install the fuel filter. Contaminated fuel WILL DAMAGE the fuel system components.
Caterpillar STRONGLY recommends the use of advanced efficiency (high efficiency) primary fuel filters. Advanced efficiency fuel filters are designed in order to better protect diesel engines that have higher injection pressures and closer tolerances. Use of primary fuel filters that are NOT advanced efficiency fuel filters will result in shortened fuel system component life. Caterpillar advanced efficiency fuel filters are the preferred primary filters for Caterpillar engines.
Severe working conditions can shorten the life of the fuel system. Severe conditions refer to a dusty environment and/or dirty fuel. Under severe conditions, reduce the maintenance interval to 250 service hours.
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.
Open the engine compartment. The fuel filter element is located on the right side of the machine toward the rear of the engine compartment.
Turn the fuel supply valve (if equipped) to the OFF position before performing this maintenance.
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.
