Technical Specifications

Benefits for Utility Vehicle Operators

The PU 51 × filter delivers a host of advantages that translate into tangible operational savings:

• Extended Engine Life: By preventing particulate contamination, the filter protects fuel injectors and valves from wear, reducing maintenance costs.
• Improved Fuel Efficiency: Clean fuel flow ensures optimal combustion, which can lead to a measurable increase in miles per gallon.
• Reduced Emissions: A well‑filtered fuel system contributes to lower exhaust emissions, helping fleets meet regulatory standards.
• Reliability Under Harsh Conditions: The robust design withstands vibration, shock, and temperature extremes common in commercial operations.

Installation Guide

1. Preparation: Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety during maintenance.
2. Drain Fuel Line (if required): Depending on the vehicle’s design, you may need to drain a small amount of fuel from the line to prevent spills. Use a suitable container for disposal.
3. Remove Old Filter: Unscrew the existing filter housing using an appropriate wrench. Carefully remove the old gasket and discard it.
4. Install New Gasket: Place one gasket from the supplied set onto the flange of the new filter housing, ensuring even contact with all sealing surfaces.
5. Attach Filter Housing: Screw the new filter housing onto the fuel line. Tighten to the manufacturer’s specified torque (typically 12–15 Nm).
6. Reconnect Fuel Line: Reattach any disconnected lines or fittings, ensuring all connections are secure.
7. Check for Leaks: Reconnect the battery and start the engine. Inspect the filter area for any signs of fuel leakage; tighten further if necessary.

Maintenance Tips

• Replace the PU 51 × filter every 20,000–30,000 miles or as recommended by the vehicle manufacturer.
• Inspect the gasket for signs of wear or deformation before each replacement; replace if compromised.
• Keep the filter area clean to prevent accidental contamination during future maintenance.
