Wow! Thanks for the information!

Decipha, what do you recommend for a replacement PPRV? How/where can I get one?

A few questions:

How does a properly functioning PPRV function? My current understanding is that it is a valve that dumps pressure when it gets too high. Like a pressure relief valve in a hydraulic circuit would. A spring loaded bypass if you will.

Does a pprv function better than an external regulator near the tank and why?

Not trying to complicate anything just trying to be solution oriented and also gain some knowledge and understanding as well.

I’m on board with redoing a replacement pprv if I can source one and I would like to know more about how it benefits the tune.

Am I losing something by reducing pump prime time?

Please share

Apologies if my questioning is unclear

pprv is a regulator, functions 100% identical

nope, pump prime time is good stuff thats why i created it

if you have a regulator then you have a pprv either will do the same job no prob
