REPLACE PRIMARY AND SECONDARY FUEL FILTER ELEMENTS Continued
The two tees (16)(21) and elbow (15) are made of brass and will damage easily if during removal
the switch or transmitter or hose are removed. Put a bolt or switch back in the tee when turning
it. This will prevent it from collapsing.

13. Hold filter canister (22) and remove screw (8) and washer (9) securing canister to fuel filter head (11).
14. Remove filter canister (22), gasket (12), and filter element (24) from filter head (11). Discard filter element. Wipe
canister (22) clean. Use rags. Discard filter, gasket, and rags per local SOP.
