Review on 🔧 WINMAX TOOLS AUTOMOTIVE: 16PCS Professional Diesel Engine Cylinder Compression Tester Tool Kit Set w/ Case – Ideal for Auto, Tractor, Semi by Kyle Robinson

The sensor worked a few tests and was fairly accurate between measurements, but I don't have another to compare its accuracy. The second time I tried to use it, the pressure gauge held no pressure at all. This is after measuring no more than 450 of the estimated 1000 psi on the gauge. The adapters are great and fit the glow plug threads on my two Toyota diesels (3B and 3L). This is one of the cheapest diesel fuel compression testers you can buy and if you just want a quick idea of your engine readings it might be worth buying.
