As part of the Diesel Pro® Series, the Fleetguard® FH24106 fuel/water separator with EleMax™ filter technology removes both water and contamination from your fuel before entering the fuel pump. Diesel Pro is engineered to save time and money through easier, cleaner filter changes, maximum filter life, and improved engine protection and longevity. The Diesel Pro is available in several variations. Each system offers unique features, like Water-in-Fuel sensors to monitor collected water levels, fuel heaters to maintain proper temperature, and Seeing Is Believing™ technology that tells users when to change the filter.
