ALLOSUN Fuel Injector Cleaner Tester & Adapter DIY Cleaning Tool Kit Set (Fuel Injector Tester)

Perfect tool for pulse-testing and flushing out gasoline Fuel Injectors. Easy to setup and easy to use. Comes in black padded case -- with instructions. Before using this Pulse Tester, use an Ohm meter to test the internal resistance of each injector. Should be 11-18 Ohms, with 14.5 Ohms as ideal. If one (1) or more injectors test out of spec, there's no sense going any further -- the bad injector(s) MUST be replaced. Fuel injectors that test within spec can be cleaned and re-conditioned with new O-rings, screen filter, and pintle caps. I used the "Little Parts BF08 Kit" (Amazon) for the Bosch/Motorcraft injectors -- with excellent results! Pictures show All-Sun Tester in included case, with AUS Connector installed on Bosch/Motorcraft injector and ready to go. The All-Sun Tester will pulse-test many brands and types of gasoline fuel injectors -- NOT for Diesel injectors !! Tester clamps connect to your 12-volt battery; red to positive, black to negative. Some reviewers attempt to use NINE-VOLT batteries to power the injector tester -- DON'T do it !! The All-Sun tester requires a full 12 volts in order to fire the gummed-up injectors and get them completely clean. I resistance-tested and flushed 2 sets of 8 injectors(16 total) by removing them from the engine. They can be resistance-tested (with Ohmeter and connector) ON THE CAR, IF you can get at them !! With the Tester set on "Mode 4 - Continuous", the injectors can be flushed with Carb/Injector Cleaner, such as "Berryman Chemtool Carb & Fuel Injector Cleaner (Amazon) by spraying into the inlet side of the injector while the Tester is on the "Continuous" Mode. The pulse-tester and Chemtool combination does a great job of cleaning out the gummy residue that builds up in the injectors due to the use of Ethanol in today's gasoline formulas. I was able to restore my old (146,000-miles) fuel injectors to as-new condition, using the All-Sun Tester, AUS Injector Connector, and the Berryman Chemtool to flush out the gummy stuff. With today's fuel injectors costing from 40 - 80 dollars each, the cost of the tester and connector easily pays for itself with just one injector flushing. When the job was completed, both my wife and I noticed a slight boost in performance, and the numbers are better at the gas pump, too !

Overall works as advertised, does its job. But it could be better. Some basic improvements like longer leads and maybe a bit better fuel injector connector adapters to make the whole thing a bit more comfortable when using. Still, it does the job well and I'm happy with it especially for the price.

It did a good job cleaning the injectors on my G37. However it can be a little cumbersome for one person. The leads should be longer. Not great for ergonomics. I ended up using a portable starter booster battery for power which gave me more room to work. Also, I had to disconnect-reconnect power in order change modes. Otherwise it worked well. A couple of tips... protect the case from the brake cleaner because it will melt the plastic. And apply the spray pressure slowly and secure the injector or it will pop out of the cleaner. Good product for the price.

It did keep the noid light lit for 1 second each test. I am not sure if it pulses rapidly or just stays on the whole test time because I just tested it with an injector current test noid light. However, All you need is a pulse that stays on a equal time for measuring the pressure drop across all injectors. So this is pretty good at for the price. If it dies prematurely, I will update my review. No update-still all good.

Injector got clogged, parts store didn't have any in stock. Needed my truck for work the following week. What to do? Amazon to the rescue. Delivered the next day, cleaned 4 injectors, fixed the issue, saving me $400 in new injectors. Thank you Amazon and thanks to whichever Chinese kid made this.

Easy peezy. Worked like a champ. I wired an old injector plug to it.

The injector tester worked really well. However hooking up the injector to the tester is very tough.

This review is for the ALLOSUN EM276SET Fuel Injector Tester & Adapter DIY Cleaning Tool Kit. 2/24. I've had one of these testers for years, and the tool has saved me many dollars in repair costs. I gave the original tool to one of my kids, so I ordered this tool to replace it. Seems as if nothing has change in the tool over the years. If you have a stuck injector, this will get the injector going again, unless the injector has suffered an electrical failure. Nothing will help an injector that has suffered an electrical failure. Oh, don't fall for the "rebuilt, or, re-manufactured " injectors. All they are are cleaned injectors with new O-rings. The first tool that I had did not have the optional parts for putting cleaners through the injectors. Wow, what a concept. Any how, for the money you would be well off having this tool in your toolbox. Buy a set of NOID light testers (they're cheap) for making sure there's a signal to the injector, and your all set. If the tool works for you one time, well, then you got your investment back.
