MANN‑FILTER Fuel Filter WK 853/12 – For Passenger Cars

The MANN‑FILTER Fuel Filter WK 853/12 is a high‑performance, OEM‑grade component designed to protect the fuel system of passenger vehicles. Engineered with precision and built to meet stringent automotive standards, this filter delivers reliable filtration across a wide range of operating conditions.

Key Design Features

• Advanced Filtration Media: Utilizes a multi‑layered cellulose‑based media that captures particles as small as 5 µm, ensuring clean fuel delivery to the engine.
• Durable Construction: The filter housing is made from high‑strength polypropylene, resistant to corrosion and capable of withstanding typical fuel system pressures up to 2.5 bar.
• Compact Size: With an outer diameter of 80 mm and a height of 176 mm, the WK 853/12 fits seamlessly into most passenger car fuel lines without requiring modifications.
• Low Pressure Drop: Designed to maintain a pressure differential below 0.5 bar, minimizing impact on engine performance while providing maximum protection.
• Easy Installation: Features a quick‑connect fitting that allows for rapid replacement without the need for specialized tools.

Performance Characteristics

The filter’s performance is validated through rigorous testing, including:

• Particle Retention Test: Demonstrated >99.9 % removal of particles in the 5–20 µm range.
• Flow Rate Assessment: Maintains a flow rate of 120 L/min at 1.0 bar pressure, ensuring adequate fuel supply for modern engines.
• Temperature Resistance: Operates effectively from –40 °C to +80 °C, covering extreme climates encountered by passenger vehicles worldwide.

Compatibility and Applications

The WK 853/12 is engineered for a broad spectrum of passenger cars. It is commonly found in models such as:

• Volkswagen Polo (2001‑2024)
• Seat Ibiza (2002‑2009)
• Skoda Fabia (1999‑2008)
• Other European passenger vehicles that require a standard 80 mm fuel filter.

Its universal design allows it to replace OEM filters in these models without compromising vehicle performance or emissions compliance.

Installation Guidelines

1. Disconnect the battery to ensure safety during maintenance.
2. Relieve fuel system pressure using a dedicated pump or by draining the tank.
3. Remove the existing filter and note its orientation for correct placement of the new unit.
4. Attach the WK 853/12, ensuring a tight seal on both ends to prevent leaks.
5. Re‑pressurize the fuel system and check for any abnormal pressure drops or leaks.
6. Reconnect the battery and perform a short test drive to confirm normal operation.

Maintenance Tips

• Replace the filter every 20,000 km or as recommended by the vehicle manufacturer to maintain optimal fuel quality.
• Avoid using the filter in high‑contamination environments for extended periods; consider a higher‑grade filter if operating under such conditions.
• Inspect the filter housing for cracks or deformation before installation; replace if any damage is detected.

Benefits of Choosing MANN‑FILTER WK 853/12

• Engine Protection: Prevents abrasive particles from reaching critical engine components, extending service life.
• Fuel Efficiency: Maintains optimal fuel flow, contributing to better combustion and reduced fuel consumption.
• Reliability: Consistent performance across a wide temperature range ensures dependable operation in diverse climates.
