9. Check for uneven dirt patterns on your old element.

Your old element is a valuable clue to potential dust
leakage or gasket sealing problems.

• A pattern on the element clean side is a sign that

the old element was NOT firmly sealed or that a dust
leak exists.

• Make certain the cause of that leak is identified and

rectified before replacing the element.

• Press fresh gasket to see if it springs back.

• On a radial seal element the gasket surface is the

inside diameter of the open end cap.

• Make sure the gasket is seating evenly, if you don’t

feel the gasket is seating evenly for a perfect seal,
you may NOT have protection.

• Recheck to see if the sealing surface in the housing

is clean, or if the element is the correct model
number. It may be too short for the housing.

10. If required, also change the secondary filter. Refer
