MR CARTOOL V308 Injector Cleaner Machine 4-Cylinder, 110V Injector Cleaner Tester Machine Ultrasonic Fuel System Injection Cleaning Kit for Gasoline Diesel Car Motorcycle

Good unit for the money, cleans injectors good

This fuel injector cleaner/tester works well right out of the box. Ultrasonic cleaner is fairly large at around 1200 ml and has decent depth for cleaning a variety of parts. It is not heated, though. I used the A-Team Ultrasonic Carburetor Cleaner from Amazon as a cleaning solution and used Isopropyl alcohol at 92% for the test fluid. Cleaned and tested 8 injectors first day taking 4 at a time through each test. Several injectors were bad to start so I ran through several ultrasonic cleaning cycles, removed the screens, and reverse flushed before testing. What's really nice is the number of fittings supplied with this set. In this case, the fittings for reverse flush were a different than size than for testing. While this accommodates injectors of various voltages, it also allows you to adjust the pressure to your operational needs. The results were an awesome aerated spray pattern on each with similar flows across all injectors (within 2ml). One thing to note is never use anything corrosive as a test fluid as it will destroy the pump and seals very quickly. The manufacturer recommended the alcohol which worked well for me especially since test fluid is difficult to actually procure. If you can find it, it tends to be very expensive. If using on injectors for every day drivers, alcohol as a test fluid is fine.

I Bought this unit to clean our injectors for our race cars. I have used it a few times and it works great for the price. It has several cleaning options and a ultrasonic cleaner on top. So far so good.

The machine works well so far. I’ve only used it twice but it performs as expected. It definitely has less features than others in the same price range and not much for directions for operation.

The injector cleaner machine works right out of the box—I bought it specifically to clear out carbon buildup in my fuel system. Idle, accelerate, leakage, injection volume and other full project test, LED screen real-time display data.The first time I used it, the ultrasonic cleaning worked fantastically, but the injector test wouldn’t start. I contacted the seller, and they resolved my issue super quick. Turns out, I was using the wrong test fluid! For injector testing, you can use 99% medical alcohol and paraffin.Now, I can clean and test four injectors at once—Ultrasonic + Heated Cleaning quickly removes the most stubborn carbon build-up.The 2000mL cleaning tank lets me clean multiple injectors simultaneously, doubling my efficiency! Highly recommend this machine—worth every penny!

The media could not be loaded.

Its very limited, it will not clean the injectors while running the injectors in the ultrasonic bath to allow pulsing the injector while in the ultrasonic fluid....not bad tho you can work around it works pretty good to test flo and atomization at a specific pressure as well as testing leakage...

I put it through all of its functions. We pulled 2 fuel rails from a yard for our stock car. The V309 cleaned, tested each one. The volume cylinders are clear and well lit. The fittings were tight and we had NO leaks. Definitely worth every penny.
