as required.

NOTE: Raised locators on fuel filter canister must be

indexed properly with slots in mounting base for

correct installation.

5. Install new filter element onto mounting. Be sure

element is properly indexed and firmly seated on

base. It may be necessary to rotate filter for correct

alignment.

certain dust seal is in place on filter base. Hand

tighten ring (about 1/3 turn) until it “snaps” into

the detent. DO NOT overtighten retaining ring.

“click” is heard and a release of the retaining ring is

felt. A plug is provided with the new element for

plugging the used element.
