Universal Fuel Injector Tester and Cleaner Tool Kit, DIY Cleaning Tool Kit, 8 Pulse Modes, 4 Wire Dual Channel for 2 Fuel Injectors, 8 Size Cleaning Adapters, 12V/5V Output Power

I was fumbling about trying to diagnose a fuel heavy situation with a GM 8.2l Big block. I have no clue why I didn't just buy one of these in the beginning. Along with a decent fuel pressure gauge, this is a life saver for diagnosing injector fuel delivery. Then, with a can of carb cleaner, I ran my factory injectors through a couple pulse cycles and... holy cow, they are back in spec, which is a good thing because OEM injectors for the 8.1l are not cheap! It is not a super complicated device, it pulses either 5v or 12v in one of 4 preprogrammed modes. I found that mode 7 (lots of short pulses) worked best for diagnosis in my situation as they were intermittently sticking. After a little bit, I could even tell by ear when they were good or bad. I also cleaned them using mode 7.

This was an inexpensive method for freeing up and cleaning the injectors for my 50 yr old Italian sports car. Saved me an enormous amount of money. Several different modes, which worked well. Intuitive and easily to use, it is a great addition to my tool kit.

Thought this was a great little set to clean injectors with. It has everything you need to clean injectors with, just need to get the right carb cleaner that has the wider tip to use with the kit.. I recommend getting "Berryman B-12 Chemtool Carburetor Choke Cleaner 16oz" It is recommend that you have 1 person to help operate the controls and 1 person to hold everything together otherwise there could be a huge mess everywhere. It was very easy to operate, hooks directly to a car battery, and was able to go thru all of the cycles to ensure the injectors were operating properly. Saved me time and money from having to send off injectors to getting cleaned. Highly recommend!

Works but I broke one connector with little effort. Could benefit from a bigger gauge wire and better crimp on the terminals. Still like the product, just needs a bit more on the wires terminals.

I used this to test and clean my fuel injectors as part of an engine rebuild. The product worked well and I recommend it...but I do have some notes: 1) The "cleaning adapters" let you insert a fuel injector, and then place the adapter and injector on a can of carburetor cleaner. I tried 4 different brands of cleaners. Most leaked between the cleaning adapter and the can. One brand (STA-BIL) did not leak: it has a different type of button on the can (a large "comfort" button), with a 4mm stem underneath. The other brands (O'Reilly, et al) have a smaller "standard" button with a 3.25mm stem underneath. These leak. This is despite using the o-rings that come with this tool. In other words, to prevent leaking the stem of the can must be 4mm to achieve a tight fit in the adapter. The provided o-rings do not prevent leaking when using a smaller 3.25mm stem that does not fit snuggly into the adapter. This is an inconvenience, but not an insurmountable problem. 2) When using the STA-BIL carb cleaner that fit tightly into the adapter, it maintained a lot of pressure (a good thing)...but is hard to hold together when the fuel injector is closed. You will probably want to set the tester to a continuous mode, start the testing, and then spray the cleaner. (If you try to start spraying the cleaner first, you will have trouble holding the injector, adapter, and can together while initiating the testing.) 3) The modes are basically: Off; Low Power: single cycle, short burst, long burst, continuous; and High Power: single cycle, short burst, long burst, continuous 4) The tester basically is just turning power on and off rapidly...simulating what the vehicle does. Perhaps "exerciser" is a better word than "tester". 5) The tester does not actually evaluate the fuel injector in any way. 6) The tester takes standard 12 volt DC power. You can connect it to your car battery or use any 12VDC barrel connector power supply that provides at least 2 amps. 7) The high power modes are useful if the fuel injectors are stuck (such as they may be if they have sat for a while with ethanol fuel in them). In this case, the low power modes may not cycle the injectors...but the high power modes may cycle them just fine.

First, all vendors appear to offer the same thing, even if some are different color. First the good: 1. A functioning one (see below) works. I don’t think you’d want this if you run a repair shop, but for us weekend guys, it will do that job. 2. It’s very straightforward in its operation. So you can’t screw it up. the bad: 1. The first unit I received died after checking 2 injectors. ok, it happens but it points out the flimsy construction of all of these. 2. You’ll receive a bunch of “tubes” to connect the injector to. in my first shipment, 2 of them were not drilled all the way through so injector cleaner was impossible to reach the injector. Of course the one I needed had to be one that was defective (of course). So when you get them, the first thing you should do is taker the red straw from your carb cleaner can and make sure the opening goes all the way through. You’ll immediately see what I’m talking about. 3. When you push the tubes the injectors push in to on top of the carb cleaner can, the connection truly sucks. Be prepared to waste a lot of cleaner. Sometimes you’ll get lucky and hold it in exactly the right way, but most of the time cleaner leaks all over. it does not however prevent the cleaning action to work, it just wastes cleaning fluid. 4. The “plastic box” containing the circuit board is made of a plastic that will smear and melt when it comes in contact with carb cleaner. Seriously folks, you couldn’t use a better material and charge 5 bucks more? As with most things made overseas today, it’s a race to the bottom on material quality. Summary: My second unit works. These units will be ok, just be prepared for a minimum amount of frustration using them. These clearly will not last a long time, they are the definition of a disposable product. A shame, as some of us would pay more for quality construction. So go ahead and order, just keep your perspective on what it is you’ll be getting.

Was perfect for what I was doing. This is not a real fancy injector cleaner, but it got the job done. I will definitely use if again. I let a friend use it and it helped him determine he needed to o replace a few injectors.

This injector tester and cleaner is great. Had everything I needed to test my injectors and cleaned them perfect. I highly recommend this product.

Works well. Trusted 8 modes in all working order. The reset button that comes with this device is handy and the products that come are all included.
