Yeah, the pressure doesn't hold well at all on initial startup and I have to basically 'prime' the system before I waste energy on the starter by over-cranking.
I've had this regulator on for well over a year, but that doesn't mean that it can't go bad, right? I still have a few old ones laying around that should still be good, so this weekend I'll drop one of those back on and see if that cures the problem and perhaps replace my adjustable regulator.
Thanks for the prompt response
