So I took off the fuel lines in a rush. The line that does not have the filter is the actual fuel line that goes to the FPR. Then the one with the filter is the Return line? Does that sound right?

Pretty sure it's the other way around. I don't think you want to be filtering the return line.

Fuel flow =
tank, pump, high pressure feed line, filter, fuel rail, injectors, fuel pressure regulator, low pressure return line, tank...

^^ That is 100% correct. Try finding a few pictures about how to hook up an aftermarket FPR.
