4. Setup Instructions

Follow these steps to prepare the kit for operation:

  1. Prepare the Canister: Unscrew the top cap of the 1000ML stainless steel canister. Ensure the canister is clean internally before first use.
  2. Add Cleaning Fluid: Use the provided funnel to pour the appropriate fuel system cleaning fluid into the canister. Do not overfill.
  3. Secure the Canister: Screw the top cap back onto the canister tightly. The hook design allows for easy hanging and movement of the canister during use.
  4. Connect Air Source: Connect an external air source to the air quick connect fitting on the pressure regulator valve. The pressure gauge will display the air pressure.
  5. Attach Cleaning Nozzle/Adapter: Select the appropriate cleaning nozzle or adapter for your specific cleaning task (e.g., intake system, fuel system). Connect it securely to the outlet hose of the canister.

5. Operating Instructions

Perform cleaning procedures carefully, following all safety guidelines.

  1. Connect to Vehicle: Depending on the cleaning task, connect the appropriate adapter/nozzle to the vehicle's fuel system or intake manifold. Ensure a secure connection to prevent leaks.
  2. Adjust Pressure: Rotate the pressure regulating valve to adjust the pressure to the recommended level for the cleaning fluid and vehicle type. The customized pressure gauge provides clear readings.
  3. Start Cleaning (Intake System): For intake system cleaning, insert the cleaning nozzle into the intake manifold. Start the vehicle's engine. The pneumatic cleaning technology will atomize the cleaning fluid, removing carbon deposits.
  4. Start Cleaning (Fuel System): For fuel system cleaning, connect the kit to the fuel rail. Remove the vehicle's fuel pump fuse to prevent the vehicle's fuel pump from operating. Start the vehicle's engine and allow it to run until it stalls naturally, indicating the cleaning fluid has been consumed.
  5. Monitor Process: Observe the cleaning process. The kit is designed for efficient and thorough cleaning of various components including TWC, intake manifold, throttle valve, and exhaust pipe.
  6. Finish Cleaning: Once cleaning is complete, turn off the engine. Relieve any remaining pressure in the system before disconnecting the kit.
  7. Reassemble: Reinstall the vehicle's fuel pump fuse (if removed) and reconnect any disconnected fuel lines or intake components.

7. Troubleshooting

Refer to this section for common issues and their solutions.

ProblemPossible CauseSolution
Fluid leakage from connectionsLoose connections, worn seals, incorrect adapter.Ensure all connections are tightened. Inspect seals and O-rings for damage and replace if necessary. Verify the correct adapter is used for the vehicle.
No pressure or low pressureAir source not connected, regulator valve closed, leak in the system.Check air compressor connection. Open the regulator valve. Inspect all hoses and fittings for leaks.
Cleaning fluid not spraying effectivelyInsufficient pressure, clogged nozzle, incorrect fluid viscosity.Increase pressure using the regulator. Clean the nozzle. Ensure the cleaning fluid is suitable for the kit.
Fittings do not match vehicle fuel linesVehicle-specific fuel line design, incorrect fitting selection.The kit includes a variety of adapters. Carefully select the correct adapter for your vehicle's make and model. Some vehicle models may require specialized adapters not included in this universal kit.
