Alex,
In my opinion it depends on what fluid you are returning. You are right if 100
per cent liquid fuel is returned. Now if 100 percent vapor is returned,
returning
to the top of the fuel tank will significantly reduce the back pressure. Because
one of the most important function of the return line is to allow vapor
to escape the fuel system, therefore preventing potential vapor lock, I believe
returning to the top of the tank is a better option.
