What is the guage rading requiremts? Sorry, I tried to use search feature. #30 psi or 100 psi for plummed after the filter with plunger LP?

 

There shouldn't be much more than 15psi anywhere in the system 'cept for the IP, unless you're running a high-pressure pump/regulator setup of some kind. Piston pump will run around 15psi, stock pump around 7psi.

I used a 15psi gauge. Easier to see small fluctuations. Runs close to pegged most of the time.

 

Thanks Ace. Is it an Autometer? In trying to keep all guages the same, I would need to check if Autometer's Z series comes in 15 psi.

 

I have the Autometer Carbon Fiber, post filter. I got a tapped banjo from Genos and installed a bleed screw, needle valve for shutoff and a snubber to keep the gauge steady:

I'm running a $10 25 psi water pressure gauge myself.

On my Bypass regulator I run a dampened Barry Grant Gage
