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 David Padilla

Bought to clean the injectors on several cars I own. What you throw in the gas tank will never do the job of any of these devices with the right concentrated cleaning solution. For less than $100 you get a kit that looks like it will work with multiple vehicles. Be sure to flush the pressure vessel and piping in both directions before use. There was a lot of dirt and metal shavings in the tank/hose and adapters. Check each one carefully before use. In addition, the air cartridge at the end of the regulator must be replaced with a standard cartridge. The thread was the same and it went straight in and was air straight with a piece of teflon tape. The gauge is off to match my air compressor, so I wouldn't trust it. The valve to open and close the liquid flow works great, no leaks. Are there better settings? Absolutely! But for a quality setup with adapters, you will pay 5-6 times more. It is enough for hobbyist/DIY. As other reviewers have mentioned, be sure to flush the tank, lines, and adapters with gasoline or something before use. I even used an old t-shirt and a stick to wipe down the inside of the tank. Be sure to close the fuel pump return line before use to prevent liquid from flowing back into the tank. Also, be sure to disconnect the fuel pump and make sure the check valve is working to keep the cleaner from spilling back into the tank. One more thing that should be mentioned. It looks like the regulator also works as a check valve. When the air hose is disconnected, the cylinder still holds pressure.
