KEEP ALL PARTS CLEAN FROM CONTAMINANTS. CONTAMI-
NANTS MAY CAUSE RAPID WEAR AND SHORTENED COMPONENT
LIFE.
NOTE: Place identification marks on all hoses for installation
purposes. Plug all hoses and all the ports in the fuel
filter base. This helps prevent fluid loss, and this
helps to keep contaminants from entering the sys-
tem.
