2004 R1150RS 47k fuel drain diagram cap to tank plate

My two drain lines from fuel cap to tank plate are different lengths and lost track of which is which. Is one line longer than the other and is there a good diagram of which goes where. This bike has had the canister removed.

If the canister is removed then both lines daylight to the atmosphere so it doesn't matter which is which.
 
That's what I thought but I'm short on one and its a stretch to make one connection. I don't recall if I ever cut one. Any measurement as to what the vent lines are out of the factory?
 
Just an educated guess from when I had my 2004 R1150RT tank open for fuel pump and filter replacement. The shorter line may go to the vent / tip over valve (probably the wrong technical term) and the longer one goes to the filler cap water drain. The vent / tip over valve connection is farther forward of the filler cap water drain connection, if I remember correctly.
