Review on 🔍 Enhancing Engine Performance: Leimo Cylinder Compression Leakdown Diagnostics by Rob Allen

The quick connector on the end of the hose was leaking. I tried a new o-ring, teflon tape and silicone gasket. Nothing worked. I didn't have time to go back and order a replacement, so I cut off the hose and installed a new barb and clamp quick disconnect. After that it worked great. The instructions aren't clear or precise, but if you're familiar with this type of tool, you can get it working. Once eliminated and calibrated, it works fine.
