'83 C10 TBI swap

So I have a "90 Suburban that I am using for a donor. I mean complete, drove it home. Has 158,000 miles.

I am in the process of switching everything , and I mean everything, from the front seats forward. The '83 is just about ready to receive its new(er) parts, In getting it ready I had wondered about the fuel system, been searching and seen several say 5/16 is used for return line on TBI, the '83 has 1/4 return. The Suburban is 5/16 return.

Haven't decided if I am going with '87 sending units and pumps or frame mounted pump.

So my question is, will the 1/4 return work with the TBI?

I pretty sure I will just change it out and do it the way the 'Burb is, but kinda wanted to ask and just post something about the project.
