Detroit DD15 Fuel Water Separator

The P551011 is designed for fuel systems using the DAVCO Fuel Pro 482/483 processor. The filter element helps separate water and capture fuel contaminants to help protect the engine's fuel system.

Water and particulate contamination can contribute to fuel-system wear and poor engine performance. Regular replacement of the fuel-water separator is an important part of maintaining a heavy-duty diesel fuel system.

DD15 Fitment

Donaldson lists P551011 in its filtration products for Detroit DD13, DD15, and DD16 engines. The specific application is the DAVCO Fuel Pro 482/483 chassis-mounted fuel water separator.

Important: Verify the DAVCO fuel processor model and existing filter part number before ordering. P551011 is specifically associated with Fuel Pro 482/483 systems and should not be assumed to fit every Detroit DD15 fuel system.

Why Replace the P551011 Fuel Filter?

A clogged or saturated fuel filter can restrict fuel flow and reduce the effectiveness of the fuel filtration system. Replacing the P551011 at the appropriate service interval helps maintain fuel flow and water-separation performance.

The Donaldson P551011 is a direct replacement filter element for applications calling for this specific Donaldson or compatible OEM filter number.
