6. Wipe the inside of the shell clean of any contaminants.
7. Inspect the O-ring and replace if damaged. Lightly lubricate the O-ring with the fuel or oil in which
it will be used, and position it on the head.
8. Install a new element onto the nozzle of the filter head. Twist and push the cartridge until it bottoms
against the step on the nozzle.
9. Lift shell up to the housing head, making sure the head O-ring is in
place. Align shell bolts so they do not interfere with inlet and outlet
piping. Rotate bolts over clamp top half (see photo). Note: Small O-
rings on bolts do not seal, but just hold washers next to bolt head.
Tighten all bolts to 33 ft-lbs, alternating in a criss-cross fashion.
10. Open isolation valves and the vent valve so that the vessel slowly
bleeds air from the top vent while filling the housing .
11. Close the vent when the housing has filled. Check all fittings and the
head/shell junction for leaks.
