Factory plumbing in 5/16".

You might want to stay with the 5/16" to avoid using weird sized couplings
to connect to the radiator and the CD4E.
You can always size up to the remote filter housing, and then reduce to go back to the line.
This is favorable to plumbing a bigger line all around.
A bigger line means more oil and a slower flow through.
