I did exactly as Cab was showing. Next best thing to having plumbed. Works quick. We use them religously everytime we surf.

I picked up the 750 and used the tsunami to fill a 400 on top of it. Now i am filling both my 400's as much as possible in the surfside, on top of the 750. Absolutly love the tsunami pump and the quick connect fittings shown above.

I even ran into another skiers choice boat last weekend and let him throw one of my bags in and i filled him up with the pump. Needless to say, he is upgrading bags now.
