PRECAUTION
Fuel Pressure and Servicing Fuel System Releasing
Fuel in the fuel system remains under high pressure when
the engine is not running.
1. Before disconnecting any fuel line, release the fuel pres-
sure from the fuel system to reduce the possibility of injury
or fire.
(1) Connect the SST to the fuel pressure relief valve
(Schrader@valve), located on the fuel distribution pipe.
(2) Place the SST drain hose in a suitable container.
(3) Depress the pressure relief button until the pressure is
released.
Alternate method
(1) Disconnect the inertia fuel shutoff switch.
(2) Crank the engine for 15 to 20 sec. to relieve the
pressure.
2. Use a rag for protection from fuel spray when disconnect-
ing the hoses.
3. When inspecting the fuel system, use the SST.
