Works for what I needed. Simple to use. Seems like it will hold up. I would recommend getting a 110v dc power supply to run it. It does come with battery connectors but a wall plug was more simple. Only thing I noticed was it would run out of fluid before the tank indicated empty. Kinda like the bottom of the hose wasnt held at the bottom of the tank. Overall I am glad I bought it. Used it to test old injectors on a new motor and to test a utv injector.

Really cool!
Very nice and affordable injector tester. I treat fuel injectors as a maintenance item and this is great to have on hand. It’s compact and affordable. Easy to connect, setup and works great with a 12v battery or power supply.
Seems to be durable enough too. Obviously not something I’ll use often but happy to have it! Foxwell generally makes good tools. I have a scanner from them that I have used for 5 years without issue.

Great for engine builders
This is an excellent quality injector tester. It easily applies equal pressure to the back of both injectors allowing you to compare the performance of each one in both flow and spray pattern. I plan to use this with my new injectors to ensure that they are matched for a performance engine, I am going to be building over the summer.
The various adaptors that it includes shoud fit almost any common gasoline automotive or motorcycle injectors. It includes all the accessories you will need to properly test your injectors.
The unit itself is compact and should fit any workbench. It's also easy to pack up and store. The pump is not very loud, and the device is easy to use following being included instructions.
This works very well for testing injectors and is a great value for performance, engine building or diagnostics.

Neat fuel injector diagnostic bench tool with automatic RPM simulator.
My vintage project car recently developed an aggravating stutter at idle, leaving me completely puzzled. Rather than blindly tossing cash at replacement parts or paying outrageous shop fees to have my fuel delivery system professionally analyzed, I decided to invest in a diagnostic bench tool. Can be a fun project, right? I needed something that could replicate engine conditions right on my workbench to help me identify the culprit. This particular FOXWELL JT200 dual-cylinder machine cleverly mimics real driving conditions by automatically ramping up from a low idle to redline, allowing you to observe the atomization quality through transparent graduated tubes. You can even manually lock in a specific engine speed to target exactly where a hesitation occurs, and it conveniently ships with multiple adapters to fit traditional electronic fuel injection nozzles. Unpacking the unit, I was immediately impressed by the heavy, rugged feel of the metal components and the tight structural fittings. Setting it up was straightforward after connecting the power leads to an old twelve-volt battery I keep charged in the garage. I mounted two of my suspected engine nozzles side by side, secured the rail, and started the automated testing sequence. Watching the test fluid turn into a fine mist is oddly satisfying, and it instantly revealed my hidden problem. While one nozzle sprayed perfectly, the adjacent one simply dribbled sad, uneven drops into the clear plastic cylinder. The side-by-side liquid volume test confirmed the faulty unit was flowing significantly less liquid than the manufacturer specifications demanded. I loved how easily I could visualize the exact mechanical fault, giving me absolute confidence to trash the bad part and order a single replacement rather than a whole expensive set.
Despite the huge money-saving benefits, my testing experience was not entirely perfect. The provided instruction booklet is terribly basic, lacking essential details about menu navigation and test parameter settings, forcing me to figure things out through pure trial and error. Additionally, the printed volume markings on the collection cylinders are quite faint and require squinting under bright garage lighting to read accurately. Another mild concern is the internal pump pressure, which remains fixed at around twenty-five pounds per square inch. Since many modern fuel rails operate at much higher pressures, this machine might fail to expose certain high-pressure leaks. Finally, filling the tiny fluid reservoir requires a very steady hand because the entry port is absurdly small. Nevertheless, this device firmly established itself as a highly valuable diagnostic asset in my home shop, taking the frustrating guesswork out of engine tuning and repair.
Bottom line:
This FOXWELL JT200 fuel injector diagnostic bench tool is a fantastic investment for anyone tired of blindly replacing engine components to fix a persistent misfire. While the included documentation is heavily lacking and the fluid reservoir is annoyingly small to fill, the ability to visually verify fuel atomization easily outweighs those negatives. It empowers home mechanics to confidently identify clogged or weak fuel delivery systems without relying on expensive professional labs. It permanently earned a spot on my workbench. Very good product overall that gets 4 stars in my book and I can confidently recommend it to all DIY-ers.
Pros:
1. Visual spray pattern is extremely clear.
2. The metal build quality feels robust.
3. Automatic speed simulation works wonderfully well.
4. Saving money on diagnostic fees rules.
5. Included adapters fit many common sizes.
6. Operating the controls is highly intuitive.
7. Testing two units together saves time.
8. Safe operation away from hot engines.
Cons:
1. The included instruction manual is useless.
2. Cylinder volume markings are barely readable.
3. Operating pressure remains fixed rather low.
4. Fluid reservoir port is annoyingly small.

Reliable
I've been using Foxwell brand accessories in my shop for many years, so decided to get this tester which satisfied me as well. Firstly, this tester simulates speed of engine automatically which starts from fast to slow like exactly real driving condition. Second, it comes with tubes which keeps fluid away from high temperature, so it's safe to use it anywhere. Third, the price in compare to other brands is way more cheaper and affordable. Highly suggested fir accuracy.
