WARNING:
-
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable
mixtures are always present and can be ignited. Failure to follow these instructions may result in personal injury
-
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, which can cause a fire
hazard. Failure to follow these instructions may result in personal injury.
-
Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any
fuel-related components. 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.
-
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.
-
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.
-
Do not use any tools. Use of tools may cause a deformity in the coupling components which can cause fuel leaks.
NOTE: During the repair or replacement of fuel-related components, all fuel liquid and fuel vapor openings shall be capped, taped or otherwise
appropriately protected to prevent the ingress of dirt or other contamination. All caps, tape and other protective materials shall be removed prior to
installation.
