Finally some Dany's Mag swap progress, and fuel line routing questions?

Maybe a better question, should the 3 port filter be before the regulator?
Currently the filter is AFTER the regulator.
If we put it BEFORE the regulator it would end up standing upright, under the alternator.
It seems to me that 3 port filter would work better standing upright with the 1/4 vapor return on top.
The plan is to try to run the lines on the outside of the subframe as far as possible, maybe going on the bottom of the subframe to get around the front suspension?
has anyone here run them anywhere but on the inside of the front subframe (factory location)???
this was the only pic 20190731_132212 (2).jpg of the regulator/filter I had on the computer at the moment.

thanks guys!!
