MANN-FILTER Fuel Filter WK 940/19 – For Utility Vehicles
The WK 940/19 fuel filter from MANN‑FILTER is engineered specifically for utility and commercial vehicles that demand reliable protection against contaminants in the fuel system. Its robust construction, precise filtration capability, and ease of installation make it a preferred choice for fleet operators, maintenance professionals, and vehicle owners who require consistent engine performance.
Key Design Features
The filter’s design incorporates several critical elements that ensure optimal operation:
- High‑Efficiency Filtration Media: The WK 940/19 uses a multi-layered media system capable of capturing particles as small as 0.5 µm, thereby safeguarding fuel injectors, pumps, and combustion chambers from wear.
- Robust Housing Construction: Crafted from durable polypropylene with reinforced seams, the housing resists cracking under high pressure and temperature variations typical in heavy‑duty applications.
- Threaded Mounting System: The filter features a standard 1/2” NPT threaded connection that fits seamlessly into most utility vehicle fuel lines without requiring adapters or modifications.
- Integrated Pressure Relief Valve: A built‑in pressure relief mechanism protects the filter and downstream components from sudden pressure spikes, extending overall system longevity.
- Clear Indicator Window: The transparent window allows quick visual inspection of media condition, enabling timely maintenance decisions without disassembly.
Performance Specifications
The WK 940/19 delivers consistent performance across a wide range of operating conditions:
| Parameter | Specification |
|---|---|
| Pressure Drop (at 10 psi) | ≤ 0.8 psi |
| Maximum Operating Temperature | 120 °C |
| Minimum Operating Temperature | -40 °C |
| Flow Rate (at 10 psi) | ≈ 250 L/min |
| Filter Life (under normal conditions) | Up to 30,000 km |
Compatibility and Applications
The WK 940/19 is designed for a broad spectrum of utility vehicles, including but not limited to:
- Commercial trucks and vans (e.g., Volvo, Steyr, MWM, Renault)
- Construction equipment such as excavators, loaders, and backhoes
- Agricultural machinery like tractors and combines
- Industrial generators and power units that rely on diesel or gasoline fuel systems
Its standard thread size and universal mounting make it a drop‑in replacement for many OEM filters across these vehicle categories.
Installation Guide
Installing the WK 940/19 is straightforward, yet precision ensures long‑term reliability:
- Preparation: Verify that the fuel line is clean and free of debris. Use a suitable solvent to wipe the connection area.
- Threading: Align the filter’s threaded end with the fuel line opening. Hand‑tighten until snug, then use an adjustable wrench for an additional half turn, being careful not to overtighten and damage threads.
- Sealing: Apply a thin layer of high‑temperature sealant or gasket material if recommended by the vehicle manufacturer.
- Verification: Refill the fuel tank, start the engine, and check for leaks. Observe the pressure gauge to ensure it remains within normal operating limits.
Maintenance Recommendations
Regular inspection and timely replacement are essential for maintaining optimal engine performance:
- Inspect the indicator window every 5,000 km or after significant fuel contamination events.
- Replace the filter if the pressure drop exceeds 1.0 psi at 10 psi operating pressure.
- Store unused filters in a dry environment to prevent moisture absorption by the media.
Benefits for Fleet Operators
The WK 940/19 offers tangible advantages that translate into cost savings and operational efficiency:
- Extended Engine Life: By trapping fine particulates, the filter reduces wear on fuel injectors and pumps.
- Reduced Maintenance Intervals: The durable media and low pressure drop allow for longer service intervals without compromising performance.
- Consistent Fuel Quality: Even in harsh environments where fuel contamination is common, the filter maintains clean fuel delivery.
- Easy Replacement: Its standard threading eliminates the need for specialized tools or adapters.
Conclusion
The MANN‑FILTER Fuel Filter WK 940/19 stands out as a reliable, high‑performance component tailored for utility and commercial vehicles. Its robust construction, precise filtration capability, and user‑friendly installation make it an indispensable part of any vehicle’s fuel system maintenance strategy. By choosing the WK 940/19, fleet managers and vehicle owners can ensure that their engines receive clean, protected fuel—leading to improved reliability, lower operating costs, and extended equipment lifespan.
