I have almost completed all the plumbing changes required for the Buffer Valve addition, and have also fabricated, and installed an access port manifold.

My problem is that the pressure gauges I was using are basically cr_p!!! The readings were off by 10 psi from when I had initially calibrated them. What I need is at least one reliable gauge (suction side) that is fairly small, and can be easily panel mounted. Anybody got a good source?

P.S. I'll be posting some pictures of the plumbing changes momentarily (need to switch computers).
