I got this to find a vaccum leak on a few vehicles I have been working on and it made it 10x faster! Smoke feature works great. I got the one with both gauges but haven't found an application where those are useful yet so I am unsure of if they're even worth getting or if they work really but for the price you can't go wrong.

This was the first time I've used a smoke tester and I didn't have any major issues. There are a few adapters in the kit that are not explained in the instructions but I was able to rig up what I needed. I used this on a 2006 PT Cruiser and was quickly able to see smoke come out. I recommend doing this inside or on a day with zero wind. A light breeze makes it very difficult to see the leak point. Note that some cars you need a bi-directional diagnostic tool to open the tank purge valve. I couldn't use the manual option because it's located on top of the tank and there is no way to access it without lowering the entire tank.

Versatile detection with 2 modes—our EVAP vacuum exhaust fuel leak tester offers two practical modes. The air mode is perfect for identifying if there are any leaks, while the smoke mode assists you locate the leak point accuarately.
Stay informed with dual high-precision gauges—our smoke machine includes a pressure gauge and flow meter that monitor smoke flow and pressure changes in real-time. The flow control knob allows you to adjust smoke output for optimal results across various testing conditions.
Our fuel pipe diagnostic tester comes with auniversal adapter, cone adapter, EVAP adapter, inlet port adapter, 8 cap plugs, power cord clip, valve core wrench, smoke tube, and refueling bottle. Before use, remember to add 10-20 ml of baby oil or mineral oil (not included)

Versatile Testing Power - Works on EVAP, Fuel, Exhaust, And Intake Systems

The VEVOR smoke machine leak tester allows you to test a variety of vehicle systems. With this smoke machine, you can work on the intake manifold, fuel tank, exhaust system, EVAP system, or even different pipe fittings. You can use it for practically any automotive diagnostic task. It works with all systems, eliminating the need to switch between tools. It helps you find even the most minor leaks by sending smoke or air through any system you connect it to. 


Using this machine helps to avoid frustration and to save time and effort. This smoke machine enables you to achieve precise results without the technical hassles, whether you're a professional trying to serve more customers more quickly or a do-it-yourself enthusiast. 


VEVOR Smoke Machine Leak Tester With Built-In Air Pump (8L/Min, 19 – 23 PSI)

The integrated air pump of this leak detector produces an impressive 8 liters of smoke per minute while maintaining a steady 19–23 PSI pressure. You do not need to look for an additional air compressor or pump that lets you start your diagnostic test right away. Every test runs smoothly, quickly, and dependably thanks to the built-in pump's steady flow. 


The design makes the machine incredibly portable. Additionally, the machine operates more quietly and effectively thanks to its internal air pump, which reduces vibration and maintains a tidy, peaceful workstation. You can detect even the most minor cracks or leaks by the steady, thick smoke output. It is also well controlled to avoid overloading your system.


Dual Detection Modes (Air & Smoke) - Find And Pinpoint Leaks With Accuracy

With its two detection modes, air mode and smoke mode, the VEVOR smoke machine leak tester makes work easier. Each mode has its own button, so switching between them is simple. In Air Mode, the gadget uses airflow to help you rapidly identify leaks in a system. It's quick, easy, and practical, much like your first check. After you find a leak, you can switch to Smoke Mode to create visible smoke, which will help you pinpoint the exact location of the leak. 


The two-step procedure provides the speed and accuracy required for professional-level diagnostics. With the integrated air pump providing steady pressure, both modes run smoothly. Additionally, this dual-mode setup guarantees that you always have the appropriate testing technique for the job. 


VEVOR Smoke Machine Leak Tester With Dual Digital Gauges And Flow Control - Precision Monitoring in Real Time

With the leak detector, you can track changes in pressure and smoke flow in real time thanks to its two high-precision digital gauges: a flow meter and a pressure gauge. Together, these tools enable you to determine not only whether a system is leaking, but also the extent of the leak. The flow meter indicates the amount of smoke being delivered, and the pressure gauge indicates the system's strength and stability.


If you need less smoke or more for a large pipe, the adjustment is simple thanks to the flow control knob. You can adjust the smoke output to fit your particular testing condition with a simple twist. It guarantees consistent outcomes for all systems, including vacuum, fuel, exhaust, and EVAP. With the digital display, you can read the numbers and make well-informed decisions.


Complete Accessory Kit - Everything You Need in One Box

The VEVOR smoke machine leak tester comes with a complete accessory kit to make your job easier. The package includes a universal adapter, a cone adapter, an EVAP adapter, an inlet port adapter, eight cap plugs, a power cord clip, a valve core wrench, a smoke tube, and a refueling bottle. You can connect to multiple systems without needing additional parts, as each accessory fits different diagnostic setups.


Everything fits perfectly and functions as a unit. The cone adapter and universal fittings ensure compatibility with various vehicle types, and the cap plugs help seal openings during testing. The DC12V power cord clip makes it simple to connect straight to your vehicle's battery and provide immediate power.


Safe & Simple Operation - 10–20 ml Baby Oil or Mineral Oil for Clean Smoke Output

The smoke detector uses just 10-20 milliliters of baby oil or mineral oil, producing stable, clean smoke without damaging your car. You don't require costly or specialized fluids. You can start your test with just a few drops of oil. This design minimizes waste and eliminates any overpowering chemical odors.


The machine is equally easy to operate. Power, air, and smoke controls are all prominently marked, and the indicators guide you through each step. You can easily adjust the flow rate, start and stop the smoke output, and monitor the gauge readings. The metal body and internal safety mechanisms also guard against overheating or excessive pressure.
