It's ideal for operators of IOTI Series DK, LANDINI Alpine, and compatible LIEBHERR or GEHL equipment. A key benefit is its effective removal of contaminants, ensuring engine longevity.

Its primary function is to remove contaminants such as dirt, rust, and water from the diesel fuel before it reaches the engine's sensitive components like injectors and pumps, thereby protecting the engine and ensuring optimal performance.
You must verify compatibility using the part number WK 718/7 against your vehicle's make, model, year, and engine specifications. Cross-referencing with the listed OEM part numbers (e.g., LIEBHERR 11346800, YANMAR 11980255810) or consulting your vehicle's service manual is essential.
The filter has a height of 111 mm, an outer diameter of 76 mm, an M20x1.5 thread size for the exit, and a gasket with an outer diameter of 65 mm and an inner diameter of 57 mm.
No, the MANN-FILTER WK 718/7 is a disposable filter. It is designed to be replaced, not cleaned. Attempting to clean it will not restore its filtration capabilities and could damage the filter media.
Replacement intervals vary based on operating conditions and fuel quality. Always follow the recommendations in your vehicle's owner's manual. As a general guideline for commercial vehicles, replacement every 10,000-20,000 miles or annually is common, but check your manual.
This refers to the standard metric thread size of the fuel outlet port on the filter. 'M20' indicates a nominal diameter of 20 mm, and '1.5' indicates the pitch (distance between threads) in millimeters.
Yes, fuel filters like the WK 718/7 are designed to trap particulate contaminants and often incorporate features to help coalesce and separate water from the fuel. However, significant water contamination may require additional filtration or system checks.
A clogged fuel filter is a likely cause. Replace the MANN-FILTER WK 718/7 with a new one. Also, check for air leaks in the fuel lines.
A severely blocked filter can restrict fuel flow. Replace the filter and ensure the fuel system is properly primed.
Ensure the filter is correctly tightened. Check that the gasket is seated properly and that the mounting surface is clean and free of damage. Replace the filter if the gasket appears damaged.
While this filter helps remove water, a persistent warning may indicate a larger issue or a saturated filter. Replace the filter and inspect the fuel tank for water accumulation.
Compatibility Verification: Before installation, confirm that the WK 718/7 part number matches your specific vehicle's requirements. Cross-reference with your owner's manual or consult a parts specialist using your vehicle's make, model, year, and engine type. Ensure compatibility with OEM part numbers like DIECI BHC5045, GEHL 270979, LIEBHERR 11346800, MCCORMICK 3677987M1, MULTICAR 1140330, WEIDEMANN 1000178758, or YANMAR 11980255810 / 12900455801.
