Fuel injection lines MUST only be used once. Discard all fuel injection lines after use.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Make sure that the caps for the fuel lines remain in position until the fuel line is positioned near the corresponding ports to prevent contamination. Ensure that the areas around the rail and fuel lines are thoroughly clean before continuing this procedure. If any parts are worn or damaged, use new parts for replacement. Cleanliness is an important factor. Ensure that no debris gets introduced into the fuel system during the installation procedure. If any parts are worn or damaged, use new parts for replacement.
Turn the fuel supply to the OFF position.
Disconnect the battery. Refer to Operation and Maintenance Manual, "Battery or Battery Cable - Disconnect".
