A/C question
I am in the process of getting my A/C back in operation on my '69 (small block). The system worked well until a hose burst and then the engine was rebuilt so I'm just now getting it together. I have replaced all the hoses,drier and O-rings and have installed everything. I have pulled a vacuum using a vacuum pump and an old R-12 manifold/gauge set. I want to leave it overnight to see if the vacuum holds. My question is this- when you close off a side of the gauge set with the large ****, is the gauge itself still open to the system or is it also closed. In other words does the shut off close at the center inlet or at the outlet to the system? Thanks for any input!
