What is the usage method of fuel injector cleaner?

[DeAlessandra]

The usage method of fuel injector cleaner is: 1. Start the engine and warm it up until the cooling fan activates, then turn off the engine; 2. Locate the engine's fuel inlet and return pipes, disconnect the inlet pipe, and block the return pipe; 3. Remove the vacuum hose at the top of the fuel pressure regulator and install the pressure cleaning tank; 4. Use connecting hoses and transition joints to link the special fuel with the main fuel supply pipe, and disconnect the original vehicle's electric fuel pump power circuit; 5. Turn on the ignition switch, start the engine, and let it run until the fuel injector cleaner is completely consumed and the engine automatically shuts off (this process takes about 10 minutes), completing the cleaning of all fuel injectors; 6. Reverse the installation steps to remove the pressure cleaning tank, detached connectors, gauges, connecting pipes, reconnect the fuel inlet pipe and vacuum valve, reconnect the fuel pump circuit, and restore the vehicle's original fuel supply state.
