help interpreting pressure readings

[msrichmond]

Ya know, for some reason, I am just now seeing this question and pic.
Of course, an AC line being close to exhaust equipment will most assuredly increase the hi side pressure. Or low side pressure.
INSULATE now. We would usually use fiberglass based exhaust wrap, it comes in rolls….have at it!!

We had a guy last summer that had his accumulator and piping right on top of his exhaust who was obviously having trouble with performance. We finally figured it out from pics what was going on. He was mysteriously reluctant to step up to the plate and do the required insulation.
You can have the best engineered system, and if you surround it with exhaust piping and such, it just won’t work. Seems like common sense but he didn’t want to believe us.

I am in the process of rotating the compressor 90 degrees to send these lines away from the manifold.
