FOXWELL JT200 Fuel Injector Tester Machine, Visualize Spray Pattern & Injection Volume, Automatic Engine Simulation 2-Cylinder Fuel Injection Tester Kit for Φ9~14.5mm Injector
About this item
- 【Sprayability Test - See Spray Pattern at a Glance】FOXWELL JT200 fuel injector tester machine provides a clear visual of spray patterns to identify clogged injectors quickly. A proper spray pattern means cleaner combustion, smoother acceleration, better fuel economy, and less carbon buildup -helping you catch issues before they become costly repairs.
- 【Uniformity Test - Measure Injection Volume with Milliliter Precision】The transparent graduated cylinders provide clear, precise visualization of flow rate differences and leak conditions, allowing you to quickly identify underperforming injectors. Find the faulty injector without replacing the entire set. No more guessing -stop replace all injectors when only one is bad.
- 【Automatic Engine RPM Simulation Mode】Simulates engine speed automatically -from fast to slow, simulate real driving conditions. Adjustable test duration from 30 to 600 seconds supports quick checks or extended testing for more accurate, reliable diagnostics
- 【Manual Engine RPM Control Mode】Manually adjust rotational speed in ±50 RPM every 0.5 seconds, covering a wide range from 100 to 9900 RPM. Ideal for targeted testing at specific engine speeds during advanced troubleshooting.
- 【Safe, Clean, and Easy to Read】Designed for safe use anytime, anywhere. The sealed test tube keeps test fluid away from high temperatures that could cause flammability, and the clear measurement marks make results easy to read. The test fluid is reusable, keeping running costs low.
- 【Works with 6V/12V MPI Vehicles & Motorcycles】Compatible with 6V/12V MPI top-feed injectors for vehicles and motorcycles. Includes a full set of Φ9–14.5mm adapters. Powered directly by the vehicle's 12V battery for convenient operation

Q&A
Q: Will it work with my vehicle or motorcycle?
A: FOXWELL JT200 fit for most 6V/12V gasoline vehicles and motorcycles, it comes with three adapter sizes (Φ9-11.3mm, Φ11-12.8mm, and Φ13-14.5mm)
Q: Can it clean the injectors?
A: The primary function of JT200 is to inspect spray patterns and flow rate differences. While the pressurized test fluid may flush out some debris during testing, it does not perform a thorough clean and is not a substitute for ultrasonic cleaning.
Q: How to select test fluid?
A: It's recommended to use professional test fluid, which is precisely formulated to simulate the viscosity, density, and surface tension of real fuel. This ensures accurate and comparable test results.Never use water, gasoline, or any substitute liquid
Q: Can I use cleaning fluid instead of test fluid?
A: Use only test fluid. Substitutes like clean fluid, water, gasoline will damage your tool and injectors.
