This is fantastic, I’ve used it and it works well and is easy to use. This is my new toy. I don’t mind looking for leaks anymore. This is simple enough and gets the job done. I read through the reviews and read where one person was unhappy with it. All I can say is he must have been having a bad day. It’s a great easy way to test evap systems. Just need to know where to buy some more 2 sided disc to apply to the filler neck.

This thing is genius. In the past I've had to remove a vacuum line someplace to feed in the smoke. In this case, I was looking for a leak in the evap system for the fuel tank. VERY easy to use, and I was able to very quickly find where the little furry creatures had chewed through a vent hose.

Nice quality billet aluminum well made part. It's easy to use and works well. The sealing discs are reusable but I'm not sure how many uses you can get from one. It would be nice to see replacements listed but I did not see any. I've used it once and it worked very well for me, it sealed good and was easy to use. I'd recommend it.

Unfortunately is extremely expensive for what they sell, is a piece of nice aluminum that will stik with double sided tape on the fuel inlet! You can use it for 6 times ! You have in total 6 double sided tapes ! After that trash!For the requested value I will expect a adaptor with a connection system like the factory cap ! Not a glued one, they say for the saftey of the system :))So if you need something like this think again! This is one time use only!I have order it to use it in a proffesional environment to diagnose vehicles, but will be sent back to the seller!

Had a car at the shop for an evap leak. Had a hell of time trying to se where it was leaking from. Order up this tool and bam! Leaking at the joint between the purge valve and hose that ran to the tank.
