Review on Mophorn Non-dismantle Injector Cleaner 600ML: Automotive Fuel Injector Tester and Cleaner for Petrol EFI Throttle (0-140PSI) - Fuel System Tool Set for Gasoline Fuel Injector Cleaning by Kenny Kowalewski

quality for the price I do not dispute. But you must replace the air fitting with a standard North American male fitting. I sprayed the built-in fitting with brake cleaner to break up the adhesive used, then removed it with a wrench. Also, do not use the pressure gauge on the device. Simply adjust the airflow on the compressor itself and then set the display on the device to maximum. I couldn't get the sensor on the device itself to work properly. For the price it didn't really matter. Watch the YouTube video to learn how to use it. Although it had flaws, I still give it five stars because it's a quarter the price of traditional devices.
