Adapters. Push the Injectors into the Adapters
using hand pressure only.
3. Install the Clip Retaining Fuel Injector (con-
necting it to the Injector Adapter).
4. Ensure all Injectors are properly aligned to
mate to the Fuel Rail.
5. Install Fuel Rail. Refer to X. FUEL RAIL
6. Connect the electrical connector(s) to the fuel
injector(s). Verify that the connectors
click/lock into place.
7. Connect the fuel line to the fuel rail.
8. Reconnect negative battery cable. Turn igni-
tion key to ON and check for leaks at the inlet
and outlet fittings using a commercial grade
soapy solution or an electronic leak detector.
If leaks are detected make repairs.
9. Start engine and check leaks. If leaks are
detected make repairs.
10. Check for MIL illumination.
XVII. FUEL INJECTOR ADAPTERS
REMOVAL PROCEDURE
Fuel Injector Adapter
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 Rail. Refer to X. FUEL
RAIL.
4. Remove the Injector(s). Refer to XI. FUEL
INJECTOR.
5. Remove the Fuel Injector Adaptor(s) from the
Intake Manifold.
6. Place tape or rag over the opening in the In-
take Manifold to prevent dirt or debris from en-
tering the engine, possibly causing permanent
engine damage.
INSTALLATION PROCEDURE
1. Lubricate the O-rings on the Fuel Injector
Adapter with Vaseline or petroleum jelly and
place back on the Intake Manifold, ensuring it
is properly seated.
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.
2. Install Injector of top of Adapter. Refer to XI.
FUEL INJECTOR.
3. Install Fuel Rail. Refer to X. FUEL RAIL.
4. Reconnect negative battery cable. Turn igni-
tion key to ON and check for leaks at the inlet
and outlet fittings using a commercial grade
soapy solution or an electronic leak detector.
If leaks are detected make repairs.
5. Start engine and check leaks. If leaks are
detected make repairs.
6. Check for MIL illumination.
