-
Fuel in the fuel system remains under high pressure even when the engine is not running. Before servicing or disconnecting any of the fuel
lines or fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing personal injury
or a fire hazard.

fuel-related component. Highly flammable mixtures are always present and can be ignited. Failure to follow these instructions may result
in personal injury.

This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to
follow these instructions may result in personal injury.
CAUTION:
-
If the liquid or vapor tube is damaged (torn, holes or delaminated), a new tube assembly must be installed. Do not use aftermarket
sleeving. Do not re-adhere loose sleeving material.
-
When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector
retaining clip area before separating from the tube. Apply clean engine oil to the end of the tube before inserting the tube into the
connector.
-
Fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is, therefore, essential that absolute cleanliness
is observed when working with these components. Always install blanking plugs to any open orifices or tubes.
