Mack Fuel Filter Water Separator
The Mack Fuel Filter Water Separator manages fluid quality by separating unwanted moisture from the supply stream before it continues through the system. As fuel passes through the separator body, internal passages slow the flow enough for heavier water content to settle away from the usable fuel. This process happens continuously during operation and does not rely on electronics or moving parts. By isolating water early, the separator helps prevent issues caused by condensation or contamination. The unit operates as part of the primary filtration path and maintains consistent performance under varying flow conditions. With its defined internal routing, the Mack 21737481 performs moisture separation as fuel circulates through the vehicle.
