Budget Build 5.9 for a 71 Scamp

Hey this is a bit off topic from the cam, but I am putting together a Summit cart and thinking about the fuel pump. What do folks think of the Holley Mighty Mite? The price works in my budget nicely, and I like the small size, plus folks say its fairly quiet ... Holley 12-427 Holley Mighty Mite Electric Fuel Pumps | Summit Racing
Would I need a regulator too?
