This is the one i used. The pigtails i used fit directly into the aluminum body, so i removed the smaller brass fitting and didnt use them.  The bottom supply to the pod is what was from the factory.  I need to check, but i used the pink tape that came with the regulator on the bottom connection to the pod, but did not tape the upper pigtail connections (not sure why now) pigtail photo that i used

Okay. I took a look at the regulator's installation instructions. The two small fittings are to adapt 1/4" female NPT to female inverted flare inlet connections. If the pigtail is using male inverted flare, you should have just connected directly. Since you say you removed them, then you are using 1/4" male NPT threads to connect to the female NPT connector on the regulator. You do need to use the appropriate thread sealing compound or tape (for gas, not water) on the NPT threads for them to seal. It is quite likely that since you said you did not use anything on the threads that it was leaking there and it is why you had empty tanks. The leak might not have been bad enough for you to notice when you installed the regulator but even a slow leak will empty a tank.
For your own safety, please re-do the installation with the correct tape or sealant and then check it thoroughly with soapy water afterward to make sure there are no leaks.

I'm glad you fixed the leaks. That RectorSeal looks to be quite versatile. I agree that having a small bottle of leak testing solution is a good idea. I have not included one, but I think I have a very small spray bottle that would be perfect for the job as it would not take up much space, yet provide me with a way to test for leaks.
