out of the Regulator.
6. Inspect the Regulator for any large dried par-
ticles and remove. Use a safety solvent to
remove any build up.
Use only Safety Solvents for the cleaning
of the regulator and its components. Sol-
vents such as carburetor or brake cleaners
may damage gaskets, seals, O-rings, di-
aphragms or other non-metal components.
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.
7. Reinstall the Plug. Torque until tight.
8. Connect negative battery cable.
9. Open Valve on LPG tank.
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.
10. Turn Key ON. Check for leaks at the inlet and
outlet fittings using a soapy solution or an
electronic leak detector. If leaks are detected
make repairs.
11. Start engine and check for leaks at all ser-
viced fittings. If leaks are detected make
repairs.
12. Dispose of any drained material in safe and
proper manner.
