VEVOR Compression Tester Adapter Kit, 9 Pcs Automotive Engine Cylinder Leak Down Compression Test, Accurate Dual Scale Pressure Gauge 0-300 psi, with Long Reach Hoses and Case for Engine Cylinders

Hi, Does the M14 threaded end of the hose have a built-in Schrader valve (check valve) right at the tip that screws into the cylinder, or is the valve located at the top near the quick-connect coupler? I need to use this on a small 2-stroke engine (chainsaw) where a valve at the very tip is required to avoid dead volume.
