Hose for HILL PUMP ??

I just bought a HILL pump (I think it’s a MKII? It’s outer tube is yellow and it also has a BSA sticker near the handle). Can someone PLEASE tell me what I need for a hose set up so I can use it on my Condor?? I have 2 Airforce tank adapters 1 for my scuba tank fill clamp and the other 1 threads onto the factory Hill hose BUT, it doesn’t seem to seal and be the correct connection? ANY HELP OR GUIDANCE IS GREATLY APPRECIATED….. 😕 I never used one of these before……Thanks Guys !!
