Other information:
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire.
WARNING: The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops...
Bring the engine to normal operating temperature. Connect
the Vacuum/Pressure Tester to the intake manifold. Run the engine at the
specified idle speed.
The vacuum gauge should read between 51-74 kPa (15-22 in-Hg)
depending upon the engine condition and the altitude at which the test
is conducted...
