Designed for both gasoline and diesel engines, this filter delivers superior filtration while maintaining optimal fuel flow.

Key Features

• Advanced Filtration Technology: Utilises a multi‑layer media system that captures particles as small as 0.5 µm, ensuring clean fuel delivery to the injectors.
• High Flow Capacity: Engineered to minimise pressure drop, preserving engine performance and fuel economy.
• Durable Construction: Made from reinforced polypropylene housing with a corrosion‑resistant metal filter element for long‑term reliability.
• Universal Fit: Compatible with a wide range of passenger car models, including various Chrysler Voyager and Ram Van variants, as well as many other OEM vehicles.
• Spin‑On Design: Features a screw‑on mounting system that eliminates the need for additional fittings or adapters.

Technical Specifications

Benefits for Vehicle Owners

• Engine Protection: By trapping dirt, rust, and other contaminants, the filter prevents wear on fuel injectors and pumps.
• Improved Fuel Efficiency: Clean fuel flow reduces engine friction and enhances combustion, leading to better mileage.
• Reduced Maintenance Costs: A reliable filter decreases the likelihood of costly repairs related to contaminated fuel systems.
• Easy Replacement: The spin‑on design allows for quick, tool‑free installation, making it suitable for both professional mechanics and DIY enthusiasts.

Installation Guide

1. Locate the existing fuel filter on your vehicle’s engine bay. It is typically positioned along the fuel line between the tank and the engine.
2. Disconnect the fuel line by loosening the clamp or using a suitable wrench. Be prepared for a small amount of fuel to spill; use a catch pan if necessary.
3. Unscrew the old filter by turning it counter‑clockwise until it releases from the mounting flange.
4. Remove any debris or residue from the mounting area and clean with a dry cloth.
5. Align the new WK 854/7 filter’s screw thread with the mounting flange. Hand‑tighten, then use a torque wrench to achieve the manufacturer’s recommended torque (typically 10–12 Nm).
6. Reconnect the fuel line and secure it with the clamp.
7. Start the engine and check for leaks around the filter connection. Verify that the engine runs smoothly and that there are no warning lights related to fuel pressure.

Maintenance Tips

• Replace the filter at intervals recommended by your vehicle’s manufacturer or when you notice a decline in performance.
• Avoid using low‑quality fuels that may introduce excessive contaminants; high‑grade fuel further protects the filter and engine.
• Inspect the filter housing for cracks or damage before installation. Replace if any defects are found.
