Technical Specifications

Installation Guide

1. Locate the existing fuel filter in the engine bay or along the fuel line.
2. Pressurize the fuel system to relieve pressure, then disconnect the fuel lines from the old filter.
3. Remove the old filter and discard it properly.
4. Attach the new WK 820/22 by aligning the threaded ends with the fuel line fittings.
5. Secure all connections with a torque wrench to manufacturer specifications (typically 10–12 Nm).
6. Re‑pressurize the system and check for leaks before starting the engine.

Maintenance Tips

• Replace the filter at the recommended interval or sooner if you notice a drop in fuel pressure.
• Avoid using the filter beyond its service life, as clogged elements can restrict flow and damage injectors.
• Inspect fuel lines for cracks or wear during each replacement to ensure overall system integrity.
