Luke before you start swapping hoses, put your bottle in and make sure the balance is ok for you, no point doing ALL the work if you end up hating how this feels. if it's cool you need to remove the hose from your current ASA (probably helpful to remove the hose from the a5 as well by releasing the tombstone catch and removing push bolt that holds it in)
To release the silver braid hose from the ASA, hold the ASA in something thats not going to mark it up, like a set of soft jaw grips or somesuch.....and then put a pair of adjustable spanners on the flat part of the silver elbow going into the ASA and turn anticlockwise to undo.
Then take your new ASA and wind the threaded elbow you just removed in a clockwise direction into the ASA not forgetting to clean the thread first of any old crap on there and applying a new thread seal loctite or some such.... i use some plumbing gear from work so one of the other boys on here will be able to say what exactly....
Pop your tombstone back in and you should be set. oh yeah test for any leaks...
hope this helps it may be a bit rambling but hey, i just got back from 15 hours at work.
Oh and this probably should have gone in tech troubles, sorry moddy's if i been bad
