I am looking at the backpack in particular here - http://www.omnipole.com/omnipole_backpack.htm

It's got an 80psi pump and the price looks good by what I can see but the websie looks a little flakey with some empty pages with just "Coming Shortly !" when you click onto them.

Is an 80 psi pump too much for a '12 Volt 8 amp hour' if I was trying to get 7 hours use from it. Am I likely to need a few spare batteries?

yes, a supplier from Croydon I think London area, call them with your questions, they are a good bunch of people and always been good to deal with.

They are suppliers and users and decided to upgrade the basic USA backpack, its now got a powerful motor and they moved the switch, so I assume they must have had a reason. as Helen said try the phone.

I notice this has an 80 psi pump. What is the pump output on the Shureflo backpack then?

Hi

The Sureflow is either 35 or 40 (I'm nearly certain it is 40).
