Key Features

Key Features

C100 combines fuel system flushing, intake cleaning, throttle cleaning, pressure adjustment, and adapter coverage in one portable cleaner kit for gasoline vehicle maintenance.

Non-Dismantle Cleaning

Clean petrol EFI fuel injectors, fuel lines, throttle-related passages, and fuel system components without removing the injector assembly from the vehicle.

Fuel System Flushing

Helps improve fuel supply, support fuller combustion, and reduce exhaust emissions when used with the correct detergent and connection method.

Intake System Cleaning

Supports intake system cleaning to help reduce carbon deposits, improve the oil-gas mixture ratio, and smooth idle speed under proper service conditions.

TWC Cleaning Support

The kit includes TWC cleaning joints and can be used for TWC and intake manifold flushing procedures according to the user manual.

Adjustable Working Pressure

The pressure gauge and regulating valve help adjust air pressure for better detergent sprayability and safer cleaning across different systems.

Wide Adapter Coverage

The adapter kit covers many EU, Asian, and USA cars and light trucks, including commonly used hose couplings, vehicle adapters, clamps, and nozzles.

Applications

Applications

Use C100 for petrol vehicle fuel system cleaning tasks where the correct detergent, pressure, adapter, and connection method can be confirmed before operation.

Petrol EFI Fuel System

Suitable for gasoline EFI fuel injector and fuel supply system cleaning on supported petrol cars and light trucks.

Throttle Valve Area

Supports throttle body and related intake passage cleaning with the spray nozzle kit and correct low-pressure procedure.

Intake Manifold Flushing

Can be used with TWC detergent and the TWC flushing kit through the intake vacuum pipe procedure described in the manual.

TWC / Exhaust-Related Cleaning

Supports TWC and exhaust pipe flushing steps when matched with the correct detergent, nozzle kit, engine speed, and safety setup.

Related Guides

Choose the connection method according to the vehicle fuel system layout. Confirm the fuel inlet hose, return hose, adapter fitment, air source pressure, and leak-free connections before starting the engine.

Pressure And Connection Summary
EFI Fuel SystemFind the fuel return hose, disconnect it, plug it with a suitable adapter, then connect the fuel inlet hose to the cleaner outlet hose with the proper adapter.
EFI Cleaning PressureAdjust the compressed-air source to about 40-50 PSI for EFI fuel system cleaning, then check all connection points before starting the engine.
Manual Pressure ReferenceThe manual describes adjusting air pressure within about 0.3-0.4MPa for fuel system flushing.
No Return HoseIf the vehicle has no return hose, remove the fuel pump fuse or disconnect the fuel pump power cable so the fuel pump will not work during cleaning.
Throttle / Carburetor StyleThe connection method is similar, but the air source pressure should be adjusted to low pressure, about 1-5 PSI. The manual also gives a carburetor reference of 0.07-0.35kgf/cm².
Hose IdentificationThe inlet hose is usually larger, the return hose is usually smaller, a filter is often connected on the inlet side, a buffer is often on the return side, and arrows may show fuel flow direction.
Pressure And Connection Summary
EFI Fuel SystemUse proper adapters for fuel return and fuel inlet hose connections.
EFI PressureAbout 40-50 PSI; manual reference about 0.3-0.4MPa.
No Return HoseRemove the fuel pump fuse or disconnect fuel pump power.
Throttle StyleUse low pressure, about 1-5 PSI.
Hose CheckConfirm inlet, return, filter, buffer, and fuel-flow direction before operation.
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.

Check Connections

Regularly check parts that need tightening and connection. Tighten loose parts in time to support safe operation.

Protect The Housing

Avoid rubbing the product against rough surfaces, especially the sheet metal housing.

Prevent Corrosion

Clean and protect external and internal parts that contact chemical media to improve corrosion resistance and service life.

Avoid Overload

Follow safe operating procedures, do not overload the equipment, and eliminate unsafe factors in time.

Inspect Wires And Wear Parts

Check the circuit section and replace aging wires or worn parts when needed. Regularly clean or replace consumable parts such as the oil pump and oil filter when applicable.

Store Dry

When not in use, store the C100 in a dry place. Do not store it in hot, humid, or non-ventilated environments.
