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 pipe and fuel
line hose (1) as shown in figure, and clamp hoses securely
to ensure no leaks occur during checking.
