3. Inspect Fuel Lines: Check for corrosion or damage; replace if necessary.
4. Install New Filter: Align the threaded end of the WK 842/4 with the fuel line. Tighten by hand until snug, then give an additional half‑turn with a wrench to ensure a secure seal.
5. Re‑pressurize System: Reconnect battery and restore fuel pressure using the vehicle’s service procedure.
6. Check for Leaks: Inspect all connections for any signs of fuel leakage. Tighten further if needed.

Maintenance Tips

• Replace the filter at the recommended interval (30,000 km or 12 months) to maintain optimal fuel quality.
• Avoid using the filter beyond its service life; prolonged exposure can lead to clogged pores and increased pressure drop.
• If you notice reduced engine performance, check for a clogged filter early.
• Store unused filters in a dry, cool place away from direct sunlight.
