Dan - would love that. I'm here to learn as well as to ultimately (hopefully...) diagnose and fix. I gathered the couple of parts to build the ag fitting pressure tester I mentioned in my first post by the same means - I saw a few posts here where people were using the same setup to diagnose their hydraulic system issues, and one gent posted the specific fittings he used. Communities like this one are gold and I appreciate the help.Total cost to build about $75 and he already has the gauge. I will share the procedure and sources for parts if he wants to go that route.
