Nice! At some point I will be back to you on the CO side of things. I have some ideas already on compact flow restriction (adjustable snubber orifice valve for gross throttling, followed by a needle valve)Here is the CO detection system plumbing:

(and you can see the fill whip output...)
and this detector:

made here where I live...
Absolutely. It may be the way I have to go after I bloody my forehead enough on the wall.In your case, I'm sure plumbed in QD fittings and a removeable bracket to hold the filters could easily (and artfully) be created...
Even if I can get the onboard filtration squared away, I think it would still be with a QD on the main compressor output and a QD after the filtration. That will allow me the option to run to an external filtration unit If I am filling at home base.
My "fill-panel" would also likely be detachable and could be QC'd after either onboard or offboard filtration.
