section) into the fuel delivery line.
Fuel System Pressure Retention
1. Operate the remote control switch for 10 seconds
and note fuel pressure.
Maximum pressure drop permissible is 10% in 10
seconds. A pressure drop in excess of this figure
indicates a leak in the pressure system.
2. Check by closing off the pressure line just before
the gauge.
No pressure drop - leak in pressure line to
pump or in non-return valve of pump.
Pressure continues to drop - leak in injectors,
pressure regulator or fuel rail connections.
To determine source of pressure leak close
off the fuel return line.

GENERAL PROCEDURES (Continued)
Draining Fuel
If the fuel pump is operational then it should be used if
it is necessary to drain fuel from the tank. Disconnect
fuel return line at main underbody lines and attach a
transparent drain tube. Run engine to facilitate
expedient fuel removal. Air bubbles in fuel stream will
indicate low fuel level.
CAUTION: Care should be taken to ensure
fuel pump is not run dry.
1. In situations where the fuel pump is not
functioning then:
Use a nylon 5 mm OD tube carefully inserted
down the filler neck, past the tank check valve
to the bottom of the tank to siphon the fuel.
Sedan
1. With the vehicle on a level surface and the fuel
tank no more than 1/2 full it is not necessary to
remove any fuel from the tank.
Purge Control Valve Testing
1. Detach the solenoid valve.
2. Apply 250 mm Hg vacuum to one port of the
valve.
3. Apply 12V across the solenoid terminals. Vacuum
should collapse immediately. If this does not
happen, renew the valve.
NOTE: All hardware must be correctly installed
and torqued to specification.
