Fuel filter (water separator element) with part number 3636572 from the REDX offer. This is a high-quality filter element used in modern Caterpillar (CAT) machines equipped with C4.4 series engines. This filter plays a key role in the fuel system, separating water from diesel fuel, which is essential for protecting precision injection systems in F-series machines (backhoe loaders) and other construction models.
REDX filters use advanced filter media that effectively coalesce water molecules, allowing them to be separated in the sediment bowl. This prevents corrosion and seizure of the high-pressure pump and injectors in Common Rail systems.

Filter fits newer generation C4.4 engine machines. Check cartridge dimensions: 153mm (element height) / 191mm (total).
Filter 3636572 is a cartridge (element) that is installed in the separator housing. It often works with a transparent sediment bowl (glass) at the bottom. When replacing, we also recommend replacing the housing gaskets (usually included).
Water is lethal to Common Rail injectors. If the water-in-fuel light comes on or you see water in the sediment bowl under the filter, drain the separator immediately. Replace the cartridge regularly to avoid costly injection system repairs.
The filter separates water and contaminants before the high-pressure pump.

The 153 mm dimension is the height of the filter element (body) itself, while 191 mm is the total height including the plastic stem/handle, which facilitates pulling the cartridge out of the housing.
In CAT F-series machines, this filter is usually located on the right side of the engine, in an easily accessible place, often integrated with the manual fuel pump.
The CAT C4.4 ACERT engine, in which this filter operates, uses an advanced fuel injection system that requires perfectly clean fuel. Water particles under high pressure act like projectiles on injector tips, hence the key role of the separator.
