Fuel Injector Cleaning

When performing fuel injector cleaning, the Cleaner should
be installed as close as possible to the inlet of the fuel rail.
On most vehicle models the fuel supply line can be discon-
nect directly from the end of the fuel rail, and the Cleaner
connected in its place. If not, the Cleaner can often be
connected just before the fuel rail at an alternate connection
such as a flexible rubber to steel hose connection or at the
outlet of the fuel filter.
1. Run the car until the engine is at operating temperature.
2. Place the vehicle transmission in park or neutral, apply
the parking brake, and turn off the key.
3. Unscrew the Fuel Injection Cleaner canister bottle from
the manifold assembly and pour in the appropriate fuel
injector cleaning solution.
4. Screw the canister back into the manifold assembly,
and hang the Cleaner under the vehicle's hood using the
chain provided.
5. Close the Cleaner inlet and outlet valves.
6. Close the relief valve by turning it clockwise until tight.
7. Pull out on the regulator adjustment knob to unlock it,
and adjust the regulator to fully open by rotating the knob
counter-clockwise.
8. Connect the cleaner supply hose to the outlet of the
Cleaner (Fig. 4).
9. Connect shop air supply to the Cleaner inlet. Ensure the
shop air pressure is no greater than 150 psi (10 bar)
(Fig. 5).
10. Follow the vehicle manufacturer's recommended proce-
dure to relieve the pressure from the vehicle fuel delivery
system.
11. If not done in the previous step, disable the fuel pump
by removing the fuse or relay, or unplugging it from the
power supply.
12. Locate the fuel supply line to the engine's fuel rail, and
select the best location to disconnect the supply line and
install the hose extending from the Cleaner.
13. Remove or disconnect any obstacles required to gain
access to the connection, and place shop towels under
and around the connection to adsorb fuel from the
disconnected line.
Note: To minimize fuel spillage and reduce the amount
of time the fuel line is disconnected, try to identify the
type of connection before disconnecting the fuel line, and
have the required connection adapter readily available.
