Review on WINTOOLS 1000 Psi Diesel Engine Compression Pressure Tester - Compatible with Ford, Cummins, NAVISTAR, Detroit by Khiam Burton

I bought this compression tester to check the pressure in a 5.9 Cummins cylinder. This kit contains many different components. Bottom line: this baby doesn't support a Cummins 5.9 injector, none of the parts fit in the injector bore, not to mention the sensor itself doesn't have a check valve making it impossible to get accurate compression readings, all they do is keep pumping . There are many good parts in this set, but none of them are used.
