Here is my "thought" process:

  1. I have a Cummins 6BT5.9 210 HP  engine, which returns more
    fuel than some engines(i.e. Lehman).  According to Cummins, I am
    probably returning from 3 to 6 gal per hour to the fuel tank.
    (Higher return at lower rpm/hp requirements).

  2. Because of (1), and the fact that I have only 1 return line and
    no equalizer line, I have a constant list on my boat if I do not
    carefully manage the fuel flow from the tanks. (Which, admittedly
    would be the least expensive course of action - initally).  A lack of
    careful monitoring on my part could lead, however, to a fuel spill
    out the vent line of the port tank.

  3. If I have a problem on the port side, I cannot switch over to the
    starboard tank because it has no return line.

Anyway, those are my reasons for considering a return line to the
starboard tank. Thanks for the input.

You are right Mike you need a return line and it should be in the top of
the tank so there isn't back pressure when the tank is topped off.
