just have a go at hiding them under lips - run around the sides of the engine bay, and tie them off wherever you can.
if you get the big loops out of them, it'll look a lot cleaner without having to do much work.
Alternatively you can run your vac source to a vac block and pull everything off that. mount the vac block in a location that is close to everything else, and then you only have 1 ugly looking line instead of half a dozen.
could also try going back to black vac lines - they won't stand out as much
I agree with the concensis though - clean looking engine bay - who cares about a few messy hoses.....
