PRECAUTION ON FUEL SYSTEM SERVICE
Work must be done with no smoking, in a well-ventilated area and
away from any open flames.
As fuel feed line (between fuel pump and fuel pressure regulator)
is still under high fuel pressure even after engine was stopped,
loosening or disconnecting fuel feed line directly may cause dan-
gerous spout of fuel to occur where loosened or disconnected.
Before loosening or disconnecting fuel feed line, make sure to re-
lease fuel pressure according to “FUEL PRESSURE RELIEF
PROCEDURE” in this section.
A small amount of fuel may be released after the fuel line is dis-
connected.
In order to reduce the chance of personal injury, cover the fitting
to be disconnected with a shop cloth. Put that cloth in an approved
container when disconnection is completed.
Never run engine with fuel pump relay disconnected when engine
and exhaust system are hot.
Fuel or fuel vapor hose connection varies with each type of pipe.
When reconnecting fuel or fuel vapor hose, be sure to connect
and clamp each hose correctly referring to left figure.
After connecting, make sure that the hose has no twist or kink.
When installing fuel union bolt gasket, always use new gasket
and tighten union bolt to specified torque.
When installing injector, fuel feed pipe or fuel pressure regulator,
lubricate its O-ring with gasoline.
When connecting fuel pipe flare nut, first tighten flare nut by hand
and then tighten it to specified torque.
