19. Pour 400 ml of fuel (1) and 150 ml of cleaner concentrate (2) into the beaker supplied in the kit again to start the second application.
20. Unscrew the top portion of the applicator and pour the mixture inside the tool. Reinstall the lid hand-tight and hang the cylinder from the hood striker.
21. Connect the application cylinder quick connect (2) to the fuel rail adapter (1).
22. Connect the shop air supply (2) to the application cylinder (1).
23. Adjust the pressure regulator to 70 PSI if needed and open the shutoff valve at the bottom.
24. Start the vehicle; the vehicle should idle smoothly. The cleaning procedure should last approximately 12-14 minutes. If the vehicle begins to run roughly or misfire then turn the vehicle off. The applicator is nearing empty or is empty: remove the applicator quick connect from the fuel rail.
25. IMPORTANT! Remove the shop air supply hose from the applicator before removing the lid or releasing pressure from the applicator.
