Did a great Job

Son said gas would spill over when filling up his blazer. Took this unit out the box. Hooked it up to the fill neck and immediately seen a pin hole in the rubber gas line underneath. Very impressed how well the unit worked.

Money saver!!!

This little smoker saved me from making a $1000 mistake. I have been getting a p0430 code and was only going to replace the cat instead of the whole manifold. Decided to order this and got it the next day did the test and noticed a leak from my gasket. So i was going to have to replace the whole thing again and throw $1400 bucks in the trash by just replacing the cat. Great tool to have. I will say the oils you use for this stink!!!! Avoid inhaling as much as you can and use a proper 3m mask.
