My fpr gauge is leaking when warm (its liquid filled). So i want to set it and put the bung back in. Just want to confirm the pressure.
With the vac hose disconnected its 36psi

Re: adjustable fuel pressure regulator setup
The gauge will have a bleeder/cap. Pierce it so it's open to atmosphere.
A liquid gauge when warm will give the wrong reading if it's sealed! The pressure in the gauge will effect the reading as the liquid warms.
I've pierced mine, I get the same readings hot/cold.
Vac hose disconnected I would run between 36-40psi. I'm still testing things out (but 36psi is fine, just be sure you can check your AFRs!).
