Cylinder Leak Down Tester, Dual Gauge Leakdown Detector Kit - Tu-21 Cylinder Leakage Leakdown Test Set for Gasoline Engine

good deal

worst tool I ever got, nothing work built in the cheapest way possible

Haven't gotten to use yet,seems good,could use a more in-depth user manual though

I bought this because I desperately needed it to do a leak down test on a head shop it was you know priced good with decent reviews well when I received it and went to work the next day to use it it had a hole in the line so it was no good and it was a line that I needed tried to contact customer service about it they won't do anything so do not recommend buying this for anybody

Works as it should

I bought this a couple of months ago. I ended up having surgery and was unable to use it until it was past the return date. The date is as you see it after the very first cylinder I tested. Now I can’t even return it. This thing is a piece of junk. Don’t waste your money.

Just got the tool 30min ago I tried to use it and now the threaded part is stuck in the head to get it out I’m going to have to pull my plenum and a bunch of other stuff so do yourself a favor and don’t use this unless you want to pull your engine apart

The hose will get stuck in your spark plug hole. The way the hose is Att arched will spong and it is a pain to get it out. Don’t waste your money. This tool will cost you more in the end than it’s worth.
