FUEL DELIVERY SYSTEM

FUEL PRESSURE INSPECTION

WARNING:
Be sure to perform work in a well-ventilated area and
away from any open flames, or there is a risk of a fire
breaking out.
1) Relieve fuel pressure in fuel feed line referring to "Fuel Pres-
sure Relief Procedure" in Section 6.
2) Disconnect fuel feed hose from fuel delivery pipe.
CAUTION:
A small amount of fuel may be released when fuel hose is
disconnected. Place container under the joint with a
shop cloth so that released fuel is caught in container or
absorbed in cloth. Place that cloth in an approved con-
tainer.
3) Connect special tools and hose between fuel delivery pipe
and fuel feed hose (1) as shown in figure, and clamp hoses
securely to ensure no leaks occur during checking.
