efi fuel line sizing / fuel pump

I am putting together a tpi setup on my 283, and I am getting ready to run the fuel lines. The tpi fuel rails has a 3/8" feed line and a 5/16" return. I allready have a 3/8" hard line run from when I was using a carb and I have lots of 3/8" line left over. Could I use the 3/8" for the return? or should I run 5/16" return line?
I am also looking for a external in line fuel pump for this project. As of right now I doubt it will make over 300hp so I dont need some insane pump. I am just looking for something to get it running. I was looking at the MSD-2225 pump from summit for $93. Is this any good? Also this pump has a 5/16" outlet, can I step it up to 3/8"?
Any suggestions/ help would be great!!

A 3/8 return will be just fine. Sorry, don't know the specs on the MSD pump.

Look at Mallory fuel pumps

3/8" return line is just fine. No problems at all.

I'd look at a combination made to go with each other like the Mallory 140 and their 3-port bypass regulator.

I use their 4-port bypass regulator with the GM in-tank 50 psi pump and it works real well.
