FUEL FILTER, WATER SEPARATOR SPIN-ON TWIST&DRAIN

This is a Donaldson Twist&Drain spin-on fuel filter and water separator. It screws onto the filter housing of a diesel engine to remove both solid particles and emulsified water from the fuel before it reaches the injection system. The built-in Twist&Drain valve on the bottom allows you to drain accumulated water without removing the filter, simplifying maintenance. Regular replacement helps prevent injector wear, rust, and power loss caused by contaminated fuel.
