FUEL TANK
WARNING: THE FUEL SYSTEM IS UNDER CON-
STANT FUEL PRESSURE EVEN WITH THE ENGINE
OFF.
THIS PRESSURE MUST BE RELEASED
BEFORE SERVICING FUEL TANK.
Two different procedures may be used to drain fuel
tank (lowering tank or using DRB scan tool).
The quickest draining procedure involves lowering
the fuel tank.
As an alternative procedure, the electric fuel pump
may be activated allowing tank to be drained at fuel
rail connection. Refer to DRB scan tool for fuel pump
activation procedures. Before disconnecting fuel line
at fuel rail, release fuel pressure. Refer to the Fuel
System Pressure Release Procedure in this group for
procedures. Attach end of special test hose tool num-
ber 6541, 6539, 6631 or 6923 at fuel rail disconnec-
tion (tool number will depend on model and/or engine
application). Position opposite end of this hose tool to
an approved gasoline draining station. Activate fuel
pump and drain tank until empty.
If electric fuel pump is not operating, tank must be
lowered for fuel draining. Refer to following proce-
dures.
REMOVAL
(1) Disconnect negative battery cable at battery.
(2) Release fuel system pressure. Refer to the Fuel
System Pressure Release Procedure in this group.
