If you get the transfer pump from gardiners this should fit into the tank, 1" hose will be fine, just cut the sections on transfer pump off that arent needed, push hose on, use clips to secure, then youll need 1" male to male adapter so you can join 2 hoses together and 2 more clips, then put tab on end with anothe clip,
you put tap at the end of the hose.
Ill take pics of mine later and email you them as ive done the same as you want to do, put your email address up
