MRCARTOOL V309 Fuel Injector Tester Direct Injection

I was pleasantly surprised by the cleaning results, they were great. You can test and clean 4 injectors at a time, or just clean fewer if you want to plug other ports on the fuel rail.
It's easy to use and doesn't take up much space in your garage or shop.
Perfect for automotive enthusiasts, entrepreneurs or repair shops to save money and make money.
The ultrasonic tank does a great job of breaking down fuel, carbon and dirt. The test unit also removes scale buildup.
You can install the injectors with confidence that they will work and flow properly. This is helpful for verifying new injectors and checking the balance between injectors. Or get your old injectors back in tip-top shape. You can observe injection patterns at different pressures and simulated RPMs.
It's definitely a lot of fun in the store.

Recommended, you can visually check if the injector is working properly, and it's very interesting to test the fluid recovery, very good product!

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 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.

Worth every penny! Ultrasonic cleaner and back flushing features are great. Highly recommend this machine.
