I Hate To Ask A Fuel System Question...

So, for same of arguement, let's say I bought this piece and modified it so the pickup goes right to the bottom. I can block one of the "Out" ports, and use one "In" from the tank and the other "In" from the return on the filter/regulator, correct? Sorry if I seem dense, but I HATE buying parts I can't use!
