Yes, Psi regulator is part of pump
Bought the pump thru Napa, don't remember brand.
Put a guage on port exiting pump and had 18 psi
Had 14 volts on pump while running yesterday.
Should I unplug it and hot wire 12v and ground
and restest?

Can't believe old pump and new pump are the issue.
But I swear I remember hearing the pump pressure up when
key was on before the issue, now I don't hear it.

Thanks Stumpy !
