ALLOSUN Fuel Injector Cleaner Tester & Adapter DIY Cleaning Tool Kit Set (Fuel Injector Tester)

Got this for my 1999 LS1 fuel injectors. I did not know that the tester's electrical connectors were too big to fit the injector plug. So I ordered an LS1 injector pigtail and plugged it into the tester leads. That made it easy to connect. My injectors fit in perfectly to the larger adapter but with pressure from the carburetor cleaner, it pops right out. So I used a zip tie to hold it all together as shown and that helped a lot. Working in my engine bay as I plugged the tester to the battery, I taped the tester to the fender to free up one hand. Push down onto the cleaner can and aim for your catch pan. The pulsing from the tester worked great.

It does work, but it is really a 2 person job. One to hold the injector/adapter/carb cleaner can, and the other to press the pulse button. Tried to do it myself, but only made a mess with carb cleaner shooting everywhere. I need to rig something up to hold the injector in the adapter. You just can't hold the injector in the adapter with one hand and press down on the can, then push the pulse button with the other. I had to get a kiddo to push the button while I did the other part, and it went much smoother. NOTE, WEAR EYE PROTECTION!! CARB CLEANER CAN SHOOT EVERYWHERE. Another issue is the supplied blade connectors were too big to fit into my injectors. Ended up using small alligator clips. No big deal. Last thing, make sure carb cleaner does not contact the base unit, or it will melt the plastic. Yeah, I found out the hard way. Bottom line is, yes, I would buy this item again if I had to.

It did a good job cleaning the injectors on my G37. However it can be a little cumbersome for one person. The leads should be longer. Not great for ergonomics. I ended up using a portable starter booster battery for power which gave me more room to work. Also, I had to disconnect-reconnect power in order change modes. Otherwise it worked well. A couple of tips... protect the case from the brake cleaner because it will melt the plastic. And apply the spray pressure slowly and secure the injector or it will pop out of the cleaner. Good product for the price.

Used for 2003 Toyota 4Runner 4.7L fuel injectors. Although I'm sure the injectors were cleaned in the process, I primarily wanted to make sure an injector was working properly. Considering rebuilt Toyota injectors are more than $150 each, this device saved me a lot of money.1. You can clearly hear the injector pulsing, so you know the solenoid is working.2. Using the adapter to run throttle body cleaner through, you know the injector isn't clogged.3. When using the spray can adapter, press down firmly and it will seal against the can, fill up the adapter, but nothing will flow until you pulse the injector.4. My 4Runner injector fit the adapter perfectly and made a tight seal with the old O-rings

It has all the functions it claims to have. Worked decent enough. Takes a moment to get the rhythm when you are cleaning injectors by yourself. Adapters fit as well as expected.

Pros:Simple to use. Different pulse modes and continuous spray mode. Case included. Does the job in one little somewhat convenient package.Cons:No on/off switch. Must disconnect from battery power to turn off or to change pulse modes. To change pulse mode after initial test of injector you must disconnect for battery power to reset tool. Injector test terminals are standard size which do not fit all injector terminals. Had to use jumper wire with alligator clips to attach to injector. Slightly annoying.

I bought this one over a more expensive option, and glad I did. Definitely get the whole kit with the white adapters that are used to connect the injectors and the spray bottle.The female plugs were slightly too big to fit into the electrical connection on my injectors, so I bought male plugs of the same size, some wire, and a size of connector that would work with my injectors. But I did get it to work.Make sure you get a nice seal from the straw to the white adapter, they include tape to help with that to make the straw big enough to create a seal. Hold the injector tight with one hand as you spray and then turn it on and watch the cleaner go through the injector.I used basic carb cleaner to clean the injectors, and it worked perfectly. I sprayed and let the injectors soak for an hour and then used this to confirm they were cleaned out and my car is running on all cylinders again.Worth the less than $50 I paid for the cleaner and tester, would have cost hundreds to take it to a mechanic.
