Technical Specifications

Benefits for Vehicle Performance

A clean and stable fuel supply is critical for engine efficiency, power output, and longevity. The WK 720 delivers:

• Consistent Fuel Pressure: Prevents fluctuations that can lead to misfires or reduced throttle response.
• Protection of Sensitive Components: Filters out dirt, rust particles, and other contaminants that could damage injectors, pumps, and catalytic converters.
• Improved Fuel Economy: By ensuring optimal fuel atomization and combustion, the filter contributes to better mileage.
• Reduced Maintenance Costs: Longer service intervals mean fewer replacements and lower overall ownership expenses.

Installation Guide

1. Locate the existing fuel filter in your vehicle’s fuel line. The WK 720 is typically positioned between the fuel tank and the engine.
2. Disconnect the fuel lines using appropriate fittings or clamps, ensuring that any residual pressure is safely vented.
3. Remove the old filter unit and discard it according to local environmental regulations.
4. Insert the new WK 720 into the line, aligning the inlet and outlet ports correctly.
5. Tighten all fittings securely but avoid over‑tightening to prevent damage to threads or seals.
6. Re‑pressurize the fuel system following your vehicle’s manufacturer guidelines. Check for leaks and verify that the pressure regulator maintains the set 3,8 bar.
7. Start the engine and observe normal operation. The filter should now provide clean, regulated fuel to the injection system.

Maintenance Tips

• Inspect the filter periodically for signs of clogging or damage, especially if the vehicle operates in dusty or high‑contamination environments.
• Replace the WK 720 according to the manufacturer’s recommended interval or sooner if performance issues arise.
• Avoid using aftermarket filters that do not meet OEM pressure specifications, as this can compromise engine integrity.
