FOXWELL JT200 Fuel Injector Tester, Fix Engine Misfire & Rough Idle -Visualize Spray Pattern & Flow Rate, Fuel Injection System Tester Cleaner Diagnostic Tool for 6V/12V MPI Motorcycle & Car Injectors

Stop Fuel Waste at Record High Prices: Every Drop That Doesn’t Burn Costs You Money. A faulty injector can silently waste 20–30% of your fuel without ever triggering a check engine light –no code, no warning. Don’t let a clogged, leaking, or poorly atomized injector drain your wallet. The JT200 fuel injector tester helps you pinpoint the exact faulty injector causing abnormal fuel consumption. Fix the real problem, restore proper combustion, and start saving at every fill-up – even with gas prices at historic highs.
See the Problem – Visual Spray Pattern Diagnosis. Most testers only check continuity, leaving hidden spray pattern issues undetected. The JT200 features transparent test tubes that give you a crystal-clear view of each injector’s spray pattern and atomization quality. Spot distorted sprays, uneven streams, or poor atomization instantly –no more guesswork or swapping parts blindly. As a professional technician said: “This is a game-changer. Way easier to find a weak injector than traditional tools.”
Precision Flow Measurement – Compare Each Injector Side by Side. The JT200 comes with easy-to-read graduated cylinders that let you measure and compare fuel volume against manufacturer specs and across all injectors. Clear injection volume scales and intuitive readings help you quickly identify deviations. No more “it looks fine” – get hard numbers to back your diagnosis and repair decisions with confidence.
Real-World Engine Simulation – Idle to Redline, No Engine Needed. Simulate actual driving conditions right on your workbench. Use Automatic Mode to test injector performance from idle to high-speed acceleration, or switch to Manual Mode to pinpoint issues at any specific RPM (100 – 9,900 RPM). No need to start the engine repeatedly – save time, fuel, and wear. The sealed, transparent graduated cylinders are designed for safety, preventing high-temperature flammability while allowing easy reading.
Wide Compatibility – Cars, Motorcycles & More (Not for GDI). Protect every vehicle in your garage. The JT200 includes a full set of Φ9–14.5mm adapters, compatible with most traditional EFI injectors and MPI top-feed injectors (Not for GDI injectors). Works with 6V motorcycles and 12V cars/pickups – simply connect to the vehicle’s 12V battery and start testing. From DIY home garages to professional shops, the JT200 covers you. [Note:] Use recommended test fluid. Kerosene or diesel can substitute. Do not use gasoline – its strong solvent properties may damage tubes and pose a fire hazard.
