Replacing Primary Filter-9100

Thoroughly clean exterior of filter (A) and filter mounting area.

Rotate retaining ring counterclockwise (left) 1/4 turn. Remove ring with filter.

NOTE: Lifting up on ring as it is rotated helps to get it past retaining detent.

Remove water separator from filter. Drain and clean water separator, dry with compressed air.

Lubricate O-ring with clean engine oil and install water separator onto new filter.

Fill filter and water separator with clean diesel fuel.

Index filter until longer, vertical keys are oriented away from engine. Insert filter into mounting base securely. Rotating filter may be required to obtain correct alignment.

NOTE: Notice indexing keys on filter. These keys ensure proper alignment of filter to mounting base.

Install retaining ring to mounting base, making certain dust seal is in place on filter base. Tighten retaining ring until it locks into detent position and a "click" sound can be heard.
