Features:
1.【Disassembly-Free On-vehicle Cleaning Fuel Injector Cleaner】Fuel injector cleaner can clean the fuel system, intake system and three-way catalytic converter. It cleans the entire fuel system, including the throttle valve, fuel nozzles and combustion chamber. No need to dismantle, time-efficient and labor-free.Fuel injector cleaner can effectively clean car carbon deposits, improve the air-fuel ratio, make the fuel fully burn, reduce exhaust emissions, and increase vehicle speed and engine speed.
2.【Working Pressure Adjustment Injector Cleaner】This fuel injector cleaner kit has high and low pressure cleaning function. Fuel injector cleaner tool is equipped with a 1000ml large capacity tank, a dual scale pressure gauge (measuring range:0~150psi, 0~10kg/cm2) and a pressure regulating rotary button. You can adjust the working pressure of the spray according to your needs, it will help you do the cleaning work better.
3.【Warmly Note】There are two types of electronic fuel injection systems, one is engine with fuel return pipe, and the other is engine without fuel return pipe. The connection way of the carburetor fuel system (throttle style system) is the same as that of the electronic fuel injection system. But the pressure in the carburetor fuel system must be 1~5PSI (0.07~0.35 kgf/cm2).
4.【3 Years Warranty】We aim at trying our best to offer you the best product and services to make you unworried before/after the purchase. We promise a 3-year warranty. If you have any questions or doubts, our professional technical team will help you solve the problem within 24 hours.

TWC CONVERTER CLEANING:

1. Pour the TWC detergent into the bottle.

2. Close the oil outlet valve of the cleaner, open its air inlet valve and connect the compressed air. Adjust the air pressure to about 36psi, then close the intake valve.

3. Connect the TWC flushing tool to the oil outlet pipe of the cleaner. Disconnect the Intake Vacuum Pipe which near the throttle and insert the TWC Flushing Nozzle into Intake Vacuum Pipe.

4. Start the engine, and open the oil outlet slowly which be sure to make the detergent into engine vacuum pipe very slowly. The flushing process needs about 30 or 40 minutes.

5. Keep the engine speed at 1000 rpm, accelerate once every 3~5 minutes, make the engine speed reach 2000~3000 rpm, and keep this state for 30 seconds. Then keep idling.

6. Stop the engine after cleaning and reconnect the vacuum line.

7. Start the engine at idle for about 5 to 10 minutes to drain the cleaning agent from the lines.

INTAKE SYSTEM CLEANING:

1. Pour the throttle detergent into the bottle.

2. Close the oil outlet valve of the cleaner, open its air inlet valve and connect the compressed air. Adjust the air pressure to about 70psi (5kgf/cm2), then close the intake valve.

3. Connect the spray nozzle to the cleaner oil outlet port. Remove the pipe in front of the throttle valve before flushing. Put the nozzle into the throttle body and start the engine. Then open the cleaner oil outlet valve and start flushing.

4. Keep the engine speed at 1000 rpm, accelerate once every 3~5 minutes, make the engine speed reach 2000~3000 rpm, and keep this state for 30 seconds. Then keep idling.

5. Turn off the engine after cleaning and reconnect the intake line.

FUEL SYSTEM CLEANING:

1. Pour gasoline detergent into steel bottle.

2. Close the valve of the cleaner oil outlet pipe, open its air inlet valve and connect the compressed air. Adjust the pressure regulator to a suitable pressure of 43-57psi (3-4kgf/cm2) by the air regulating valve.

3. Connect the cleaner quick connector to the fuel supply line of the vehicle's fuel system. Check all connections for leaks. There must be no leaks during cleaning work.

4. Start the engine and keep it idling, then flush the fuel system.

5. Drain out the pressure in the bottle after flushing, and then disconnect the cleaner.

6. Restore all of the pipes of the fuel system and check if there have leakage.
