Hi Spyrus,
in one picture i see stage tanks in the background. Why not use an inflator hose on the 1st stage. When you need bailout plumb in from the stage tankīs. I use Ali 80 for my diveīs. When the inboard o2 stage or the soleonid failtīs i plumb into the o2 manuall inflator on the CL. Same way for diluent site. Thanks for the time to upload the picīs.
Cheers Markku
