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

Works well.

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.

A Kant Twist Clamp works perfectly for holding the injector.Had to use direct power with a momentary switch for cleaning. The pulsing device didn’t hold the injector open to allow cleaner to flush.

It does work, but it is really a 2 person job. One to hold the injector/adapter/carb cleaner can, and the other to press the pulse button. Tried to do it myself, but only made a mess with carb cleaner shooting everywhere. I need to rig something up to hold the injector in the adapter. You just can't hold the injector in the adapter with one hand and press down on the can, then push the pulse button with the other. I had to get a kiddo to push the button while I did the other part, and it went much smoother. NOTE, WEAR EYE PROTECTION!! CARB CLEANER CAN SHOOT EVERYWHERE. Another issue is the supplied blade connectors were too big to fit into my injectors. Ended up using small alligator clips. No big deal. Last thing, make sure carb cleaner does not contact the base unit, or it will melt the plastic. Yeah, I found out the hard way. Bottom line is, yes, I would buy this item again if I had to.

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 !

The tester seems to be built well but this is only speculation since I will have to find an adapter for my injectors. The wires that connect to the injector are twice the size of what would fit on the terminals of an injector so I will be going to the store to try to find something that will work for my situation. I should note that these injectors came out of a 2000 gmc which were installed for almost a decade in the chevy/gmc line up.I was also surprised to learn that you can not use a different source for power other then a car battery. There is a battery compartment on the back of the unit but its more for storage. Guess I cannot perform this task at my bench unless I remove my battery. I gave three stars since it did not come with all the accessories necessary to perform its function and the adapter for the spray can has to be used on a can with an external neck for the nozzle.
