looking at your pics you only have two lines from the main tank, an in and an out, for me it worked best to have two vent lines out of the main tank, one feeding each header tank, it gave better filling without allot of main tank and UAT swelling and better even draining of the saddles.
Yes Stig, I would do this, it will make your fuel pump work easier and last longer.
