Automotive Smoke Leak Detector, 12V EVAP, Pump, Flow Meter

Automotive smoke machine leak detector helps you pinpoint EVAP and vacuum line leaks fast with visible smoke output at low 1 PSI pressure, reducing guesswork on sensitive systems. A built-in air pump delivers stable smoke without an external compressor, while the integrated flow meter and control knob help you spot small leaks during routine diagnostics on cars, motorcycles, and trucks.

• Delivers visible smoke to trace leak points quickly in EVAP, vacuum, and fuel vapor lines


• Maintains low 1 PSI output to test sensitive, low-pressure systems without over-pressurizing


• Uses a flow meter and control knob to help identify small leaks and confirm sealing


• Runs standalone with a built-in air pump—no external air compressor required


• Includes fittings and adapters to seal ports and lines for accurate vacuum diagnostics

Designed for hands-on maintenance and shop-style troubleshooting, this DC 12V smoke tester supports consistent low-pressure testing in tight engine bays and hard-to-reach pipelines. Thermal protection and durable metal construction help it hold up to repeat use, while controlled smoke flow improves repeatability from test to test. If you’re chasing intermittent EVAP faults, vacuum leaks, or difficult-to-locate seepage, set up the sealing kit, dial in flow, and verify results with the meter. Grab yours today and streamline your leak checks.
