heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pressure even after engine was stopped, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel to occur where loosened or
disconnected. Before loosening or disconnecting fuel feed line, make sure to relieve fuel pressure
referring to “Fuel Pressure Relief Procedure”.
• A small amount of fuel may be released after the fuel line is disconnected. In order to reduce the
chance of personal injury, cover the fitting to be disconnected with a shop cloth. Be sure to 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 (1) connection varies with each type of pipe (2). When reconnecting fuel or
fuel vapor hose, be sure to connect and clamp (3) each hose correctly referring to the figure Hose
Connection.
After connecting, make sure that it has no twist or kink.
• When installing injector or fuel delivery pipe, lubricate its O-ring with spindle oil or gasoline.
• When connecting fuel pipe flare nut, first tighten flare nut by hand and then tighten it to specified
