WARNING
!
Before starting the following procedure, be
sure to observe "Precautions on Fuel System
Service": in related manual in order to reduce
the risk or fire and personal injury.
1) Relieve fuel pressure in fuel feed line.
Refer to "Fuel Pressure Relief Procedure": in related
manual.
2) Loosen clamp and place a large cloth over end of the
high pressure fuel feed hose (1).
Slowly pull fuel feed hose (1) from the fuel delivery
pipe main joint (2).
Drain any excess fuel in hose into a small container.
3) Connect special tools (pressure gauge, pressure
hose and pressure joint) between fuel feed hose (1)
and fuel delivery pipe main joint as shown in figure.
Clamp the hose securely to ensure that no leaks
occur during checking.
CAUTION
!
A small amount of fuel may be released when
the fuel feed hose is disconnected.
Place container under the fuel feed hose or
fuel delivery pipe main joint with a shop cloth
