Help finding CO2 leak

Hello Everyone. I have a very simple CO2 setup on my kegerator but have been going through CO2 like crazy. I have used 5lbs of CO2 and Im only halfway through a sanke keg. This happened on the last one too and I thought it was because of a loose line that I missed.

I have sense gone through all of it and used soap suds everywhere and I just dont see a leak at all. I opened the CO2 valve from the tank to put pressure in the line then closed the valve. It will go from about 25psi to none in about 2 minutes or so.

I am questioning my CO2 regulator but I dont see any leaks on any of the connections it has.

Any help/thoughts are appreciated.

Quick update. I had a brand new tap laying around so I hooked that one up and it seems to be holding pressure. Guess I will need to buy a couple rebuild kits for my older taps. They both seem to have a leak…

I have one regulator that is leaking internally. Found the leak by accident while soaping everything possible and bubbles appeared at a small hole in the back. Unfortunately I could not find a rebuild kit for it so a new one was the cure.
