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.
-
Do not use any tools. The use of tools may cause a deformity in the clip components which may cause fuel leaks.
1. If servicing a liquid fuel tube, release the fuel system pressure.
2. Disconnect the battery ground cable.
3. Disconnect the fuel tube quick connect coupling.
-
Press the fuel tube quick connect coupling button and pull the fuel tube to disconnect.
Connect - Type III
1. CAUTION: Make sure the fuel tube clicks into place when installing the tube. To make sure that the fuel tube is fully seated, pull on the
tube.
NOTE: Apply clean engine oil to O-ring seals.
Install the quick connect coupling onto the tube until it is fully seated.
Disconnect - Type IV
WARNING:
-
The evaporative emissions system contains fuel vapor and condensed fuel vapor. Although not present in large quantities, it still presents
the danger of explosion or fire. Disconnect the battery ground cable from the battery to minimize the possibility of an electrical spark
occurring, possibly causing a fire or explosion if fuel vapor or liquid fuel are present in the area. Failure to follow these instructions may
result in personal injury.
-
Do not smoke, or carry lighted tobacco or open flame 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.
-
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.
-
Fuel in the fuel system remains under high pressure even when the engine is not running. Before repairing 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. 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.
