Where would my LP regulator leak?

Been chasing an intermittent propane leak. I think it must be my regulator, but i have not found a place making soapy bubbles. I will pressurize the system and then close the propane valve and watch the dial. Sometimes it will lose pressure in 2 minutes. Other times it will hold pressure all night long. Ive tried setting the regulator to different positions and cant seem to make it leak enough that i can confirm with soapy bubbles before buying a new regulator. 
Do you think maybe its leaking at the ACME nut instead? I recently bought 2 new hoses which i hoped would solve my problem. (both hoses would leak slightly). I noticed the new ACME nuts sure felt hard to turn on both hoses. Spraying soapy water everywhere i cant find the leak. 

WHAT do you mean by that highlighted statement??


LP leaks
Probably that 'gauge' (really useless cause they work on pressure and the cylinder will have pressure until almost empty---10#)
1st Stage Vent....small pencil size hole in body
2nd Stage Vent....1/2" hole in body
Body Crimp areas
Pigtail...bushing/hose connection on backside of ACME Nut
*How hard of a bend is in that pigtail (reg to cylinder should be a easy swooping bend NOT tight curve)

Hard to tell from PIC
That big knob (haven't seen one like that)....should POINT towards the cylinder in service NOT Up/Down like in PIC
What brand Reg is that?


LP Portable Leak Detector (sniffer) are inexpensive and WILL find very small leaks (roughly $33 or less) and No Messy Soap Residue
*Small leaks may NOT produce visible bubbles
