I don't think the 59SV pump is what you want. I could be wrong so anyone correct me but I believe that pump has 1/8" fittings. I think what you're looking for is commonly known as a "Red-Top" pump: 45 gallons/hour at 6-8 PSI. Part # Facet RTW506.
Where to buy one in the U.S.... I don't know but if you can find, I'd like to know.
