Product Usage Instructions

Connecting the Hose Lines

1. Disconnect fuel supply hoses (C, D) and fuel return hoses (A, B) from the engine fuel system carefully.
2. Connect proper connectors to the B and C ends of the unit and then connect the other ends to corresponding hoses on the engine as shown in Fig.01.
3. Connect the remaining ends (A, D) with proper hoses or take necessary precautions to prevent fuel leaks.

Without Return Hose Connection

1. Disconnect fuel supply hoses (E, F) from the engine fuel system.
2. Connect a proper connector to the E end and ensure the fuel outlet hose is connected well.
3. Secure the other end (F) with a stopper or by removing the fuel pump fuse.

Cleaning Process

1. Fill the steel bottle of the product with a mixture of gasoline and detergent.
2. Close the fuel-outlet pipe valve and open the air-inlet port valve before connecting to compressed air at a pressure of 0.3 to 0.4MPa.
3. Connect the product’s fuel supply adaptor to the car’s fuel system and check for leaks at all connections.
4. Start the engine to flush the fuel system.
5. Release pressure in the bottle after flushing and disconnect the product.
6. Restore all fuel system pipes and check for leaks.

TWC and Intake Manifold Flushing

1. Pour TWC detergent into the bottle and set air pressure to zero.
2. Connect the TWC Flushing Kit to the product’s output pipe.
3. Disconnect the Intake Vacuum Pipe near the throttle and insert the TWC Flushing Nozzle as instructed.

FAQ

• Q: What precautions should be taken when operating the Fuel System Cleaner?
  • A: Always wear protective gloves and clothing, stop the engine in case of a fuel leak, use a fire extinguisher during cleaning, and lead exhaust gases outdoors.

CAUTIONS

Warning

• Wear protect gloves and cloth when operating.
• Must stop engine if there have any fuel leak!
• Bind up the pipe as disconnect the pipe to avoid splash and fire.
• Please prepare at least a fire extinguisher when doing on-vehicle cleaning.
• Please lead the exhaust to outdoor when doing on-vehicle cleaning, because it contains a variety of toxic and hazardous gases.
• Please put the transmission in N and pull the brake when doing on-vehicle cleaning.

OPERATIONS INSTRUCTION

Connecting

The hose line connection of the engine with return hose is shown as in Fig.01.

• Disconnect the connections of fuel supply hoses (C, D) and fuel return hoses (A, B) of the engine fuel system (wrap the connector with towel when disconnecting the connector). Choose proper connectors and connect them to the B end and C end separately, and then connect the other ends to corresponding return hose and outlet hose of the unit. See Fig.01.
• Connect the disconnected other ends (A, D) with proper hose, or remove the fuel pump fuse, or disconnect the power cable of engine fuel pump.

Without return hose connecting

The hose line connection of theengine without returnhose is shown as in Fig.02.

• Disconnect the fuel supply hoses (E, F) of engine fuel system (wrap the connector when disconnecting the connector), and then choose a proper connector and connect it to the E end. Reconnect the fuel outlet hose of the unit well and make the fuel return hose hanging. See Fig.02.
• Stop the other end of the disconnected end (F) with a proper stopper, (use when the fuel pump has the fuel return function only) or remove the fuse of fuel pump or disconnect the power cable of fuel pump.

THE PICTURES

• Pour the mixture of gasoline and detergent into steel bottle of the product.
• Close the valve of product’s fuel-outlet pipe and open the valve of product’s air-inlet port and then connect to the compress air. Adjust the pressure of air within 0.3 to 0.4MPa ( 3 to 4kgf/cm2 ) by air control valve.
• Connect the fuel supply adaptor of the product to fuel supply pipe of the car fuel system, and open the ball valve. Check if it has some leaking between all the connections. There must have no any leaking when doing the cleaning work.
• Start engine to start flushing the fuel system.
• Drain out the pressure in the product’s bottle after flushing, and then disconnect the product.
• Restore all of the pipes of the fuel system and check there have no leaking

Note

The connection ways for carburettor fuel systems is the same to electronic fuel injection systems. The pressure in carburetor fuel system must be 0.07~0.35 kgf/cm2

• The operating procedure of TWC and intake manifold flushing:

• Pour the TWC detergent into the bottle. Open the Ball

• Valve and Air Pressure Regulating Valve to keep the air pressure as zero.

• Connect the TWC Flushing Kit to the output pipe of the product.

• Disconnect the Intake Vacuum Pipe which near the throttle and insert the TWC Flushing Nozzle into Intake Vacuum Pipe as shown.

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

• Keep the engine speed up to 1000 rpm and press the accelerator every 3~5 minutes to make the engine speed up to 2000~3000 rpm and keep this state for 30 seconds. Then keep idle speed.

• Do the flushing procedures as above until to exhaust the detergent. Then stop engine and reconnect the vacuum pipe.

• Start engine as idle speed for about 5 to 10 minutes to exhaust the detergent in the pipe.

The operating procedure of Throttle body and exhaust pipe flushing:

• Pour the Throttle Body detergent into the bottle, and close the Ball Valve of the fuel outlet pipe. Open the ball valve of the air inlet port and connect to the compressed air. Adjust the air pressure to about 0.5MPa ( 5kgf/cm2 ) and then close the Ball Valve of air inlet port.
• Connect the spray nozzle kit to the fuel outlet port of the product.
• Remove the pipe ahead of throttle before flushing as shown.
• Put the spray nozzle kit in the throttle body as shown and start the engine. And then open the Ball Valve of fuel outlet port.
• Keep the engine speed up to 1000 rpm and press the accelerator every 3~5 minutes to make the engine speed up to 2000~3000 rpm and keep this state for 30seconds. Then keep idle speed.
• Do the flushing procedures as above until exhaust the detergent.
• Reconnect the pipes and initialize the throttle.

Caution

• It must initialize the Throttle Position Sensor by automotive scan tool after cleaning. Otherwise, the fault-indicating lamp will lighten on, and PCM will record a DTC.
