Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Mark fuel lines (1) for reinstallation purposes. Remove fuel lines (1).
If, any hoses are worn or damaged, replace with new parts.Reference: Refer to the Operation and Maintenance Manual for information on when to replace the fuel lines.Install Nonmetallic Fuel Lines
Note: During installation, ensure that the hoses do not contact nearby parts. Pressure pulsations in these hoses cause the hoses to flex. Inadvertent contact with nearby surfaces will produce chafing/abrasion damage that could eventually lead to a leak. A properly installed hose will contact only the hose clips.

Loosely install clips (2). Position fuel lines (1) so that there is no contact with any other surfaces. Tighten clips (2). Tighten fuel lines using standard torque.Best Practices for Installing Nonmetallic Fuel Lines
Use the following best practices for proper fuel line installation and maintenance.
Do not twist the hose when installing, allow the hose to find the natural position.
Illustration 5 g03659618
(1) Torque wrench
(2) Back-up wrench
When torquing hose fittings, use a back-up wrench to prevent twisting as in Illustration 5.
Use the proper length of hose to prevent the hose being too tight or slack.
Keep the bending radius of the hose as large as possible to prevent kinking.

Illustration 8 g03659640
Ensure proper alignment of the grommets when installed in the fuel line clips as shown in Illustration 7. Proper alignment of the opening of the grommet with the mating faces of the clips ensures proper clamp load.
Clips should support the natural position of the fuel line and guide routing as in Illustration 8. Clips should not create strain on the fuel hoses.
Use the proper torque to all line fasteners and connectors.
Recheck all fuel lines after completing installation to look for contact with surrounding components. Fuel lines should only be in contact with rubber grommets and at the termination points.Note: All third-party installations must meet prescribed installation guidelines. Third-party components must not come in contact with Caterpillar components.
Inspect fuel lines, grommets, and mounting hardware every 500 hours. Refer to the Operation and Maintenance Manual maintenance schedule for replacement intervals of fuel system lines and components.Note: Certain components such as the side covers will need to be removed to conduct a proper inspection of fuel lines and components.The following illustrations below show proper line, clip, and grommet alignment to allow for sufficient clearance from other components. Proper alignment creates gentle bends that guide fuel lines to the termination points.
