• Robust Construction: Made from durable polypropylene housing with reinforced end caps to withstand high pressure and temperature variations typical in automotive fuel systems.
• Wide Compatibility: Specifically engineered for vehicles such as the Audi A6, A6 Allroad, and other models within the Volkswagen Group that use the 4F0127401 series of fuel filters.
• Easy Installation: Features a standard 76 mm outer diameter and 188 mm height, matching OEM specifications for seamless replacement without modifications.
• Long‑Lasting Performance: Designed to maintain optimal flow rates over extended mileage, reducing the need for frequent replacements.

Technical Specifications

Installation Guide

1. Disconnect the battery to ensure safety.
2. Relieve fuel system pressure by opening the high‑pressure line valve or using a vacuum pump.
3. Remove the old filter by loosening the retaining clamps and carefully lifting it out of the housing.
4. Inspect the housing for damage; replace if necessary.
5. Insert the new Mann Filter WK7351 into the housing, aligning the flow direction arrow with the fuel line.
6. Tighten the retaining clamps securely but avoid over‑tightening to prevent cracking.
7. Reconnect the battery and restore fuel pressure.
8. Check for leaks around the filter connections; tighten further if needed.

Maintenance Tips

• Replace the filter every 30,000 km or as recommended by the vehicle manufacturer to maintain optimal fuel quality.
• Avoid using low‑grade filters that may allow contaminants to pass through and damage injectors.
• Inspect the filter housing for cracks or corrosion before each replacement; a damaged housing can compromise seal integrity.
• Store spare filters in a dry, cool environment to preserve media performance.
