• Other Brands: Compatible with Ford Hanomag Henschel and other European commercial vehicles that share the same mounting geometry.

Installation Guide

1. Preparation: Disconnect the battery to prevent accidental ignition. Drain any residual fuel from the filter housing if necessary.
2. Removal of Old Filter: Unscrew the existing filter by turning it counter‑clockwise until it releases from the mounting flange.
3. Installation: Align the new WK716 with the mounting flange. Screw clockwise until snug, ensuring a tight seal without overtightening to avoid damaging the housing.
4. Reassembly: Reconnect any fuel lines or fittings that were removed during removal. Restore battery connection.
5. Test Run: Start the engine and check for leaks. Verify that the filter is operating under normal pressure conditions.

Benefits of Choosing WK716

• Engine Protection: By trapping contaminants, it prevents wear on fuel injectors, pumps, and other critical components.
• Fuel Efficiency: Maintains optimal flow characteristics, contributing to consistent engine performance and reduced fuel consumption.
• Reliability: Designed for long service life under demanding operating conditions; reduces the likelihood of unexpected failures.
• Ease of Replacement: The spin‑on design allows for quick swaps without specialized tools, making it ideal for fleet maintenance schedules.

Maintenance & Longevity

The WK716 is engineered to last through multiple service intervals. However, regular inspection is recommended:

• Visual Check: Inspect the filter housing for cracks or deformation after each major service event.
• Pressure Test: Verify that the pressure drop across the filter remains within specified limits; a sudden increase may indicate clogging.
• Replacement Schedule: Follow manufacturer guidelines, typically every 20,000–30,000 km for diesel engines and 15,000–25,000 km for gasoline engines, or sooner if operating in dusty environments.

Why OEM‑Grade Matters

Choosing an OEM‑grade filter like the Mann+Hummel WK716 ensures that:

• The filtration media meets exacting standards for particle removal.
• The housing material is compatible with the vehicle’s fuel chemistry, preventing degradation.
• Installation tolerances match factory specifications, eliminating fitment issues.

Conclusion

The Mann+Hummel WK716 Fuel Filter delivers reliable protection for a wide array of Mercedes‑Benz and Puch vehicles. Its precise engineering, durable construction, and ease of installation make it the preferred choice for professionals seeking to maintain engine integrity and performance over extended periods.
