EVAP Smoke Tester V3, Auto Fuel Vacuum Detector Pump Gauge Flow Meter

I drive a 20 year old truck with a v6 that had a bad idle, been chasing vacuum leaks one at a time for a long time. Finally I got this and smoked it and found a massive split right in the easiest spot to change, and I never noticed it because it was on the underside. This unit found it and I put a couple hoses on and smoothed the idle right out. Now that I've used this a few times it's pretty easy, zero to smoke test in 5 minutes. The hook is awesome, the inflatable bulb is awesome, the hoses are long, the alligator clips are decent, the oil port is decent, the oil view hole is awesome. The only small issue with it (that's not worth deducting even a single star over) is it has two speeds, and only the lower speed puts out smoke. If you wait for smoke on high speed you won't get any and might think it's broken. Click the button back to low and give it 10 seconds to start making smoke. Also you might consider getting a telescoping inspection mirror or some kind of endoscope. Making smoke come out the leak only takes 5 minutes, but actually getting your eyes on the hole can be tough.

Came with great attachments, quality is FAR better than I expected. Has everything that even the Harbor Fright machine at $549 comes with, except the pretty black case...if I REALLY want a case, I can buy one for ALOT less than the $450 difference. Even if I were still turning wrenches for a living, and would consider this VS a Snap-on or MAC machine...I could buy ten of these before I have even started to pay off the tool truck machine. Just fill it with mineral or baby oil, hook it up, adjust your flow rate, and find your leak. That simple. Find your fitting to seal onto your intake, exhaust, whatever you need to test...I recommend doing this in a garage, or on a less windy day...but your leaks will become obvious pretty quick...a simple laser pointer makes it easier, just start pointing it around, up under the dash if you are working on the AC system, the laser will get very visible in the smoke.

This smoker is great I've used it to test vacuum lines, intakes, ac systems, exhaust pipes and cab leaks. Saved my butt many times. Awesome pump.

Very good smoke machine. The only issue is the air guage reading isn't accurate. The components are very well made. All components works as described except for the air guage to show the air pressure. Ease of use and installation.

Worked great! Helped verify a suspected intake leak. Easy to use..

I purchased this to check for intake leaks on a car. I am working on. Within minutes of being delivered to my house, I had it running and had found several leaks. Since I have had it. I have found more uses for it because it works so well. I wish I would’ve bought one sooner!

machine working fine just need better way to pack the oil

Hard to beat for the price. Small, simple, puts out great smoke and pressure. Comes with very useful accessories. No complaints

Does what it says on the tin!! Easy to use and very powerful. You won’t be disappointed

Absolutely great machine! saves you ton of time when trying to locate them perished seals that let trough air. Definitely the tool to have if you working on engines. Good quality. Worth the money.

will find your leak in a secs, 5 min cut off, easy to use, Great product to have in your garage
