FRAM Diesel Spin-On Water Separator Filters
Diesel fuel usually contains a higher amount of water than gasoline or other fuels. If unfiltered, this water together with dirt detracts from engine efficiency. Unfiltered fuel also contributes to increased engine wear and tear.
Made of aluminum, diesel fuel water separators collect filtered water which can later be drained from the engine during routine vehicle maintenance. Most separators have a sensor which lets you know when the water level is getting high. Y
ou simply remove the fuel tank drain plug attached to the separator which lets the collected water and dirt flow away. It is best to drain the separator often.
