I have never done any a/c work and just installed vintage air in my 1953 3100. All seems to have went well with evacuating the system holding -29 psi overnight. When charging I admittedly got confused and I'm sure I did something wrong. Vintage Air says acceptable operating pressure ranges should be 160 to 270 psi on high side and 10 to 20 on low side. This is what I ended up with.
Looks like I am low on the high side and extremely high on the low side. Any advice is greatly appreciated. Thanks
