Throw lockwashers away. 3. Using hands, remove clamp (E) from sensor probe wires (B) and (C). 4. Using socket, loosen capscrew (F) to provide movement of fuel-water separator. CAUTION Be very careful not to disturb center filter element. Center filter element must be replaced if disturbed in any way. NOTE It may be necessary to use hammer and punch to unseat sensors (B) and (C) by tapping upward on edge of sensor retaining nut. 5. Using 1/2 inch wrench to hold sensor retaining nut (G), use 9/16 inch wrench and remove upper sensor (B) from fuel-water separator. 6. Using 7/16 inch wrench, open and then close bleed cap (H). 7. Check to see if fluid level is above upper sensor probe (B) hole by noting leakage from upper sensor probe (B) hole when bleed cap (H) is open. 8. Using 1/2 inch wrench, remove sensor retaining nut (G). 9. Using 1/2 inch wrench to hold sensor retaining nut (J), use 9/16 inch wrench and remove lower sensor (C) from fuel-water separator. 10.
