XXII. FUEL VAPOR PORT FITTING
REMOVAL
1.
Relieve the LPG fuel system pressure. Refer
to
XVIII. LPG FUEL SYSTEM PRESSURE
RELIEF.
2. Disconnect negative battery cable.
3. Remove retaining clip securing the Port Fitting
in the port and remove.
4. Loosen Hose Clamp securing the Port Fitting
in the Hose and pull Port Fitting from hose.
INSTALLATION
IMPORTANT
Port Fittings are designed for specific applications,
DO NOT any other adapter or fitting other than the
part specified by the OEM.
1. Slide Hose Clamp over the Hose.
2. Insert Port Fitting into hose.
3. Slide Hose Clamp over the end of the Hose
and tighten.
4. Lightly lubricate O-rings on the Port Fitting
with Vaseline or petroleum jelly.
Contamination of the HEGO sensor can re-
sult from the use of an inappropriate RTV
sealer or silicone spray products. Do not use
silicone sprays or hoses which are assem-
bled using silicone lubricants. Always use
“oxygen sensor safe” RTV sealant for repair
procedures. Silicon contamination will cause
a high but false HEGO signal voltage (rich
exhaust indication). The ECM will then re-
duce the amount of fuel delivery to the
engine, causing a severe driveability prob-
lem. If silicone contamination is suspected,
remove and visually inspect the sensor ele-
ment. If contaminated, the portion of the
sensor exposed to the exhaust stream will
have a white powdery coating. Always be
sure to eliminate the cause of contamination
before replacing the sensor.
5. Reinstall Hose Port into port and secure using
a Retaining Pin.
6. Reconnect negative battery cable.
7. Open LPG tank valve.
IMPORTANT:
The fuel cylinder manual valve contains an
Excess Flow Check Valve. Open the manual
valve slowly to prevent activating the Excess Flow
Check Valve.
8. Turn Key to the ON position for several
seconds, then turn back to OFF. Using a liq-
uid or electronic leak detection tool, inspect
the REGULATOR, fuel hoses and all serviced
fittings for leaks.
9. Start engine and check for leaks.
XXIII. REGULATOR PRESSURE CHECK
1. Refer to
XXIV. LPG FUEL RAIL PRESSURE
CHECK
to check the Regulator outlet pres-
sure.
XXIV. LPG FUEL RAIL PRESSURE CHECK
1.
Relieve the LPG fuel system pressure. Refer
to
XVIII. LPG FUEL SYSTEM PRESSURE
RELIEF
.
2. Disconnect the negative battery cable.
3.
Remove the Fuel Pressure Sensor. Refer to
VII. FUEL TEMPERATURE/PRESSURE
SENSOR.
Residual vapor pressure will be present in
the fuel system. Ensure the work area is
well ventilated before disconnecting any
fuel line.
4. Connect the test fitting, Hose and Gauge.
5. Open LPG Tank Valve.
6. Connect negative battery cable.
7. Turn ignition to ON and note value on gauge.
8. Relieve the LPG fuel system pressure. Refer
to
XVIII. LPG FUEL SYSTEM PRESSURE
RELIEF.
9. Remove Gauge. Install Fuel Temperature
Sensor. Refer to
VII. FUEL
TEMPERATURE/PRESSURE SENSOR.
