Hi Chip,

Actually I thought of a Whale pump: a Canadian brand from Vancouver.
Too bad they come to us Europeans at twice the price than Guzzlers come to you.
You may want to look up the Plumbing section.
I suppose the lever pulls the membrane somehow...
Thx for the link.

: Hi Eric, you might be thinking of one of the Guzzler pumps; that's probably
: your best route other than the design Ben mentioned. Run a search on
: http://www.google.com/advanced_search with "Guzzler" and
: "footpump" as key words. I also did a homemade footpump
: prototype (below) but all the bugs aren't worked out yet. I like your
: concept; why not design your own?
