Baldwin Filters PF7978 Fuel Water Separator Element

Product Description

The BALDWIN FILTERS PF7978 is a diesel fuel and water separator element designed for automotive and light-duty diesel engine fuel systems. This element-only design handles fuel filtration by separating water and capturing particulate contamination before fuel reaches sensitive injection components. It is rated to operate at a maximum pressure of 60,000 psi and is built to tighter tolerances than standard replacement filters, making it suitable for high-pressure common rail and other precision diesel fuel systems. The kit includes two O-rings and grommets for a complete service installation. Licensed technicians and diesel mechanics are the primary installers.

This element fits diesel fuel filtration applications where an element-only replacement is required rather than a spin-on assembly. Its dimensions - 3.281 inches outside diameter and 5.438 inches overall length - place it in a common segment of medium-duty diesel filter housings. Compatible cross-reference part numbers from the input data include Donaldson P550824, Fram CS10648, Hastings FF1185, International 1878042-C91, and Wix WF10149, making it a direct-interchange option for those part numbers.

Installation Notes

Installation should be performed by a qualified diesel technician or mechanic. Relieve fuel system pressure and shut off the fuel supply before opening the filter housing. Replace the included O-rings and grommets during every service interval and ensure the housing is torqued to the housing manufacturer's specification, not a value assumed from the element itself. Follow applicable shop safety procedures when working with diesel fuel.
