2 fuel lines, which fuel line is supply?

2000 F250 7.3

Under the hood I have two lines from the tank... (Fuel pump located on the rail). I am trying to determine the supply line.

The one coming off the diesel fuel filter (under the hood) Which is it? Supply or return? That should answer my question...

My chiltons manual has been no help... sure hope someone sees the by morning or I,m out of work all day... Thanks

The supply is larger than the return.
