Automotive EVAP Smoke Leak Detector With Air Pump, Gauge

Automotive smoke machine leak detector pinpoints hard-to-find vacuum and EVAP leaks fast, reducing guesswork and repeat repairs. Built with a built-in air pump and digital pressure gauge, it delivers stable airflow and controlled pressure for accurate diagnostics across fuel, intake, exhaust, and pipeline systems. Dual-mode testing lets you confirm a leak in air mode, then trace the exact source in smoke mode—ideal for shops and serious DIY users.

• Delivers dual-mode testing: use Air Mode to confirm leaks, then Smoke Mode to locate the exact leak point.


• Includes built-in air pump for quick setup—no external compressor needed for stable smoke output.


• Monitors pressure in real time with a digital gauge to help assess leak severity and test consistency.


• Fits multiple vehicles and systems: EVAP, fuel tank, intake, exhaust, seals, and pipe fittings.


• Includes a complete adapter kit plus cap plugs for faster hookups and fewer improvised fittings.

Stop chasing intermittent codes and invisible hose cracks with a leak tester designed for efficient, repeatable diagnostics. The included adapters help you connect to common ports and lines, while the pressure readout supports controlled testing so you can document results and avoid over-pressurizing. Add 10–20 ml of baby oil or mineral oil (not included), choose your mode, and follow the smoke to the fault. Grab yours today and keep leak checks fast, clean, and consistent.
