Help with figuring out return pump gph needed?

I am setting up my new 75g tank. A friend gave me an overflow box that hangs on the back, that has one single line draining down to the sump. The drain line is 1 1/2" inside diameter. The sump is 20g. LI am looking at purchasing an Eheim return pump. Return pump will have about about a 6ft . tube to travel up. Based on the info I provided, how can I figure out how many gph return I need, and which Ehiem pump to get? Is more info needed than what I provided here for making that choice? thanks
