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

The name is misleading and says they have the correct gloplug adapter for the gloplug 7.3. That's right! HOWEVER it takes about 2-3 minutes to insert and screw it into the hole as there is no gap to install the bushing between the rocker arms. If you struggle with this and tighten it all the way, you can use the tip of the needle to push it firmly against the air hole in the center of the fitting. SENSOR TO GLOPLUG ADAPTER. DO NOT BUY THIS, DO NOT, DO NOT BUY THIS UNLESS YOU WANT TO BE FILLED WITH REGRET AND DISAPPOINTMENT. I haven't tested it on other engines. Have a nice day and spend your money elsewhere.
