Fuel filters in original equipment quality from Mahle pay off in every way. These filters are available for passenger cars, buses, commercial vehicles, tug boats, excavators, and wheeled loaders. Modern injection engines require extremely clean and homogenous fuels to be delivered with as little pulsation as possible however, water and small foreign objects get into the fuel during production and transport. This can cause the engine to misfire and become un-driveable. Mahle fuel filters retain foreign objects reliably with the use of high-quality filter media to protect the fuel system against tiny dirt particles. Pressure regulation and return feed of the excess amount from the injection pump is returned back to the tank to provide the necessary constant fuel supply, ensuring that the engine functions smoothly and guarantees economic operation of the vehicle.
