This has a lot of adaptors (like two schrader valve adapters) which should work for many applications, and the build quality seems quite good. Unfortunately, everything is in Chinese, so you will need additional references to determine which adapters (and some mechanical ingenuity) you will need for your application. For a manual, you may try an internet search for "Procleen Professional Fuel Injection Cleaning System." For a youtube videos, I thought the videos for the "BG 9210 Fuel Tool" (Parts 1 and 2) by Tech Art & Automotive Abilities were very good. The youtube video "How to do a Professional Fuel Injector Cleaning On the Vehicle" by Guns and Gears was also informative to me.Also, when I got the kit, many of the adapters fell out of their storage slots. I had to refer to the sales pictures to figure out how to put the adapters back into the case. A stainless steel tube got bent slightly, but it didn't get kinked, so I was able to rebend it slightly to get it back into the blow-mold case.
