I'd remove the regulator on the inner fender. Replace it with a union fitting and put the regulator back in a box on the shelf so if you go back to the Dominator you have it. Running two regulators in series like that is asking for problems. If you need a place to tap in for fuel pressure then use a union fitting with a 1/8 NPT port on the size.  I run 20 psi to my fuel log.
