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

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.

Very useful on checking spray from your fuel injectors. Been having an issue with my 99 Tacoma injectors and a place I have purchased their so called "rebuilt" injectors. With this you know exactly what yours is doing. The pulse modes are very useful. Shutting it down and restarting like it would if it was in your vehicle. Keeping the clearer pressure to your injector was the biggest problem with it. Its all in how you set it up. Well worth my investment.

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.

I haven’t had a chance to use it yet but. I did hook one up and it did function well. I like the size and the case it comes with to keep everything together. so from first glance and just making sure it worked im happy with it for the price. easy to use and DIY friendly. its nice to not have to spend a ton of money on this type of stuff you may use only a couple times a year.

Bought this to test the injectors on my Yamaha. Found two that were in need of attention and had those professionally cleaned and mapped. Have used it a couple of times since to clean injectors on a spare bike and also on my son's bike. Expect it would work for cars as well but for me it has been bikes only. I love the different settings and ease of use.

Work good but unfortunately my injections seat was too big to use any of the included nozzles

Works great to test injector failure, but testing the spray pattern was less successful. To test the injectors "dry" as a good/bad injector, the tester worked great. I had two out of eight bad injectors. As I was trying to determine if my issue was injectors or coils, it solved my delema on what to fix, and replacing the injectors solved the problem. When attempting to test the pattern, the pressure from the cleaning fluid would frequently push the injector off of the adapter. I found I needed an assistant to hold the injector in place, while I started the cleaner flow. This might also be accomplished by clamping the injector in some fashion. Overall, it solved my problem at a minimal price, avoiding my throwing parts on the vehicle blindly to fix two "cold" cylinders

1st off, the set of orange adapters aren't drilled consistently where the spray can connects and also check that the passage from can to injector port is clear. I found that Berryman carb cleaner fit one of the adapters I had and I was able to drill to fit on another adapter to do 2 injectors at same time. To me it's impossible to hold the injector in the adapter, press on the can and activate controller while trying to view spray patterns. It's too much pressure to hold injector in adapter even when turning on 1st and then can spray. So I made a sliding lock from some old fence railing and it works effortlessly. I'm happy with it now! But I mean seriously, it's a cheap tool compared to a professional flow bench. Btw my engine is a LS LM7.

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.
