Para salir del paso está bien

Easy to use, plug and Play, if you plan on cleaning many injectors, you might get the one with the built-in pulse box.

This product worked perfectly. The only problem was that I needed to watch a YouTube video to figure it out because the instructions were in Chinese. But that wasn't worth dinging it one star for the instructions. The product consists of two white "housings" each with a small hole at one end, and a larger but different diameter hole on the other end of each housing. The larger diameter holes are sized to fit the "input" end of the fuel injector that is to be tested. The electrical cables each have alligator clips on one end and a plastic electrical connector to power the fuel injector. So pick the cable that has the electrical connector that will fit your injector. The hard part is holding everything together in order to test it. Some research led me to the realization that running an injector off of 12v CONTINUOUSLY will likely damage the injector. However, they can be powered from a 9v battery continuously. So what did was the following: 1) I plugged the proper size electrical connector into the injector that I was going to test. 2) I plugged the fuel input end of the injector into the proper sized hole in one of the two white housings. 3) I removed the spray nozzle from the aerosol can of fuel injector cleaner and pulled the protruding end of the nozzle into the end of the white housing. 4) I connected the black end of the electrical cable onto the the negative end of the 9v battery and the red end onto the positive terminal of the battery. I heard an audible "CLICK" when the connection was made. 5) Then I pressed the can's nozzle against the end of the white housing and observed the spray pattern coming from the injector. 6) I disconnected the red clip from the battery. It was actually very easy once I got the hang of it. See photos. ******************** UPDATE ******************* I still agree with most of what I wrote--however, I have some additional comments: 1) The wires are soldered to the alligator clips without any reinforcement, that is the alligator clips have tabs on them that can be easily bent over the part of the wire that is insulated. If they had done that then no stress would have been put on the wire. However, they DIDN'T do that so one of the wires broke shortly after I started using it. I stripped the wire back, clamped the tabs over the insulated part of the wire and then soldered the bare end to the clip. Then it worked as it should have from the beginning. I expect that the other wires will eventually break as well. When that happens I'll repair them in the same way. So, I'm removing one star from the review. It's still a good product--it could simply be better.

Great product. Easiest way to check and clean injectors.

Works exactly as it’s suppose to.

Work but have to be careful, spray everywhere if you do it wrong.

Besides being a day late, this is the only instructions that came with it. Luckily I already know how to use this device, but if I didn't?
