Fillkit for 300 bar scuba bottle

Hey Guys!
I'm at my wits end here. I recently bought a bobcat .22 (SUPER excited :D) and a 300 bar 6 ltr bottle to fill it. My problem is this: I simply cannot figure out which parts I need to connect the bottle to the 'cat. I know that I need to buy stuff like a hose/adapter etc etc, but which ones? Size etc? Sorry to be a bother if this should be self explanatory, but I'm a complete noob in this, and really just wanna shoot this gun :D I was planning to buy the bits from this place: http://www.bestfittings.co.uk/ 

Any help would be sorely welcome !
Cheers/ Peter
 
Thanks for helping me out guys! It's worth solid gold to have the opportunity to ask questions like these! Billydjann, could you post a photo of what you've done? Sounds interesting :) Gunnertrones, the first product code does'nt work? I think I'll call best fittings, see if they've got an advice for me (since I think thats where I'll be buying - I live in Denmark, Europe so precision airguns is a bit far off :D ) Anyway, thx again!!
