Flush out the gage hose with the test vehicle's
fuel before taking any fuel samples used for
testing.
1. Connect the fuel pressure gage to the
fuel rail.
2. Insert the gage's bleed hose into an approved
container. Do not use the 100mL beaker for
this flushing procedure.
3. Turn the ignition switch to the ON position. DO
NOT START THE ENGINE.
4. Command the fuel pump ON with the
scan tool.
5. Slowly open the bleed valve on the fuel
pressure gage, until the gage hose has
been flushed.
The FIRST fuel sample is used to test for water
or sediment in the fuel.
The first fuel sample is not to be used in the
J-44175-A tester. After the first fuel sample is
tested for water or sediment, that sample is to
be discarded. Fuel should be disposed of in
accordance with all applicable federal, state
and local requirements.
The SECOND fuel sample is to be used
in the J-44175-A tester
Use either the J-34730-FF orange-face pressure
gage or the CH-48027 Digital Pressure Gage to
obtain the samples (see figure 11). Either gages
is ethanol tolerant.
NOTE: Flush out the gage hoses with the test
vehicle's fuel prior to taking any fuel samples. Follow
the instructions included with either pressure gage.
To obtain a fuel sample from the pressure gage bleed
hose, use the 100mL beaker that is included with
the fuel tester kit (see figure 12).
