      Fuel sending unit/line size help

      So it looks like stock LS fuel line sizes are 3/8" feed and 5/16" return according to Google.

      I was hoping to just buy a sending unit with two ports and just basically drop it in and be good to go. Problem is, I can only find sending units with a 1/4" return line.



      Is that too small? Am I just going to have to add my own port for a return line?
