How To Use

How To Use

Follow the correct connection method for the target system. Always add the proper detergent, use compressed air, check every connection for leakage, and release pressure before disconnecting the cleaner.

1. Identify Fuel Hoses

Find the fuel return hose and fuel inlet hose. The inlet hose is usually larger, and a filter is often connected on the inlet side.

2. Connect The Return Side

Disconnect the fuel return hose and plug it with a suitable adapter. Wrap disconnected connectors with a towel to reduce fuel splash risk.

3. Connect The Cleaner Outlet

Disconnect the fuel inlet hose and connect it to the C100 outlet hose with the proper adapter.

4. Handle The Fuel Pump

Connect the outlet and return hose of the fuel tank. If there is no return hose, remove the fuel pump fuse or disconnect fuel pump power so the pump will not work.

5. Add Detergent And Air

Pour the proper cleaning fluid into the C100 bottle, connect compressed air to the air port, and adjust pressure for the selected cleaning task.

6. Check And Clean

Check all connection points to confirm there is no leakage, then start the engine to clean the fuel system.

Additional Cleaning Procedures

  • Throttle style cleaning: use the same basic connection logic but adjust the air source pressure to about 1-5 PSI.
  • TWC and intake manifold flushing: pour TWC detergent into the bottle, connect the TWC flushing kit, insert the nozzle into the intake vacuum pipe, start the engine, and open the ball valve slowly so detergent enters the engine vacuum pipe gradually.
  • TWC flushing time: the manual describes a flushing process of about 30-40 minutes, with engine speed raised at intervals according to the procedure.
  • Throttle body and exhaust pipe flushing: connect the spray nozzle kit, remove the pipe ahead of the throttle, place the spray nozzle in the throttle body, start the engine, and open the fuel outlet ball valve.
  • After cleaning: reconnect all pipes, drain pressure from the C100 bottle before disconnecting, and check that all fuel system pipes are restored without leakage.
Before You Order And Use

Before You Order And Use

C100 works with gasoline fuel systems, detergent, compressed air, and a running engine. Confirm safe connections, correct pressure, ventilation, and fire protection before on-vehicle cleaning.

Petrol Vehicle Focus

The product content focuses on petrol / gasoline EFI vehicles. Confirm compatibility before using it on other fuel systems.

Compressed Air Required

C100 requires a compressed-air source. Adjust the pressure according to the target system and do not use excessive pressure.

Stop For Fuel Leaks

Stop the engine immediately if any fuel leakage is found. Do not continue cleaning until the connection is safe.

Prevent Splash And Fire

Wrap pipe connectors with a towel when disconnecting them to reduce splash risk, and keep a fire extinguisher nearby during on-vehicle cleaning.

Vent Exhaust Outdoors

Lead exhaust outdoors during on-vehicle cleaning because exhaust contains toxic and hazardous gases.

Secure The Vehicle

Place the transmission in neutral and apply the brake before on-vehicle cleaning.

Before And After Operation

  • Wear protective gloves and protective clothing when operating the cleaner.
  • Use only the detergent type required for the cleaning task and follow detergent instructions.
  • Check every connection point before starting the engine; there must be no leakage during cleaning.
  • Drain the pressure in the C100 bottle after flushing before disconnecting the cleaner.
  • Restore all fuel system pipes after cleaning and confirm there is no leakage.
  • After throttle body cleaning, the throttle position sensor may need to be initialized with an automotive scan tool to avoid a fault light or DTC.
Maintenance And Care

Maintenance And Care

Regular care helps keep the C100 cleaner safe, stable, and ready for the next service job.

    Well made and comes with every adapter I could ask for. Instructions are a bit simplistic. Does what it was designed to do and does it well. I am a mechanic with 30 years experience and this complete tool does what you could spend 1000 dollars on. Waiting to see about durability as I have only used it a few times. Well worth the money.

    All the pieces are there good case for storage! Good quality, you should be able to get years of use out of it. I did two cars today and both are running much better with smoother idle and driving. It has a great case and came well packed with foam to protect the regulator gauge. Instructions are very basic so don’t expect them to cover you car, just watch you tube videos to figure it out. I used this on my Ford Flex and Subaru Outback, worked great. On the outback, I pulled the fuel pump fuse, used the large plastic connector to connect to the fuel rail. You have to connect the end of the line/hose with a hose clamp to the connector. I crimped the return hose with a pair of vice grips and a towel to protect the line, this is done so you dont just flush the cleaning fluid back into your gas tank. Filled the can with B12 fuel injector cleaner and sealed the lid. Tighten the valve at the bottom of the can before you connect your compressor hose, then you can adjust the pressure level for you car. Once the level is correct, you can open the bottom valve to allow the cleaning fluid to pressurize the line and start the car. Let the car run until it dies and the can is empty. Be careful as the cleaning fluid is very toxic. Wear eye protection and gloves. De pressurize the can with the button on top before taking the lid off or disconnecting the line. On my Ford flex the car would not start with the pump fuse or relay disconnected, so there is a piece in the kit that will fit in the line on the car and a cap to seal off that line while the tool is connected. Great stuff! Saved me a ton of money. I got this kit for about 85 dollars and picked this one because it seemed to have the most selection of adapters/connectors. A typical fuel injector cleaning service from a shop is around 60-100 dollars so after your second use you are way ahead.

    I do my own maintenance on my vehicles. 2 of which are direct injection and require extra maintenance to prevent carbon buildup on the intake valves. This allows the injection of chemicals to keep these buildups at a minimum. Nicely made also includes other tools for working with fuel injection and other parts of the injection systems. Reasonably priced for such a comprehensive tool for working with injection systems.
