Fuel Injector Tester Cleaner 8 Pulse Modes Injector Cleaner Kit 2 Fuel Injectors Simultaneously Tester DIY Cleaning Tools with 40inch Power Cord,4 Injector Cleaner Adapter,Short Circuit Protection 12V

This thing works great! I used it to test some old injectors and compare them to the new ones that I'm about to put in the Jeep and I could visibly see the difference in the spray patterns between the old and new injectors. Just a side note, go to any parts store and get a can of brake parts cleaner or carb cleaner and pull the nozzle off. If it has a little white nipple sticking up, you can use it to pressurize the adapter and the injector will spray the cleaner so you can see what it's doing. Just hold the blue adapter in the palm of your hand and use the first two fingers to hold the injector in the adapter because the pressure from the can of cleaner will make the injector fly out. Also, please remember to point the injector in a safe direction and away from your face when you press the button to activate the injector. I found the 1,2 and 5,6 settings to be most effective for basic testing. They will be listed in the instruction manual, but they're basically low and high power single and rapid pulse settings, respectively. Use with caution and I think you'll be very satisfied with it.

Great buy, & right for the price.

Got the job done!

This unit is just what I needed! Thanks for the fast shipping.

I was looking to purchase bigger injectors but wanted to take the cheap route- I bought 2 sets of injectors that had less than favorable reviews due to some injectors being DOA- enter this tester to save me the hassle of installing injectors only to learn they need to be swapped. Out of the 8 injectors, this saved me the hassle and found 2 DOA injectors- and all of this cost less than a single injector from the dealer... time and money well spent in my case- and honestly, seems like good practice to test EVERYTHING, regardless of vendor reputation- because duds do happen!

This tester work great and is of better quality than one might think for the price. Great for the occasional use. Used it to clean a set of injectors on a motorcycle, made the job go so easily. Glad to have this in my tool box.

The unit I received only worked on the first of eight injectors. No I did not reverse the polarity. Had this set-up on my assembly table with 12v battery out of my corvette. The following injectors failed to pulse when in any of the modes. Initially mode 4 was used. Went back and retested the first injector and the unit was dead. Opened up the unit by removing the four screws only to find that one of the diodes on the printed circuit board had burned up. P.S. the second set of leads are useless. You can only test one injector at a time.Update: 09-20-23Seller Kaisal re-imbursed me for the Injection Tester and sent me a new replacement free of charge.Unfortunately the second unit failed exactly the same way as the first; having cycled only one injector.I really can't say that it is a faulty fuel injector tester; but they both only cycled one time.Suspect the unit is not capable of testing my GM/Bosch fuel injectors. GM 12554271 or Bosch 0280155752. This injector is rated as 28.55 lb/hr @ 58 psi, high impedance - 13.1 Ohms with an EV1 style connector.The 6-pin diode that burned up has EBEOC printed on top and is located at position U2 on the circuit board.You'll need a 20X Jewelers Loop to verify the failed diode.

This works perfectly when it comes to pulsing the injectors for cleaning. But there’s two things that are keeping me from giving this item 5 stars;First, the adapters included are not universal for all injectors, and may not work if you’re attempting to back-flush your injectors.Second, and this is a big one for me, the plastic housing for the injector tester is prone to dissolving with certain chemicals. Unfortunately, one of these chemicals is Carb/Injector cleaner. This is a major oversight from the manufacturer, as that is the primary chemical anyone will use with this kit. If there is even a slight amount of residue left on your gloves or fingers, the plastic will turn to goo and become sticky.Other than that, device worked as intended for my purposes.
