Moving fuel pressure regulator

Moving fuel pressure regulator
For packaging reasons I am considering moving the fuel pressure regulator to the passenger side.
I would be using an adjustable FPR etc obviously.
Can anyone see any issues with doing this? I would in effect delete the OEM reg, and join the drivers side rail directly to the usual return pipe, so that I have full pressure in the return leg under the manifold.
One issue might be that the fpr sits "further away" from the injectors, but I'm not sure if this would cause problems as such.

Ideally the regulator should be as close to the injectors as possible to avoid pressure drop. Increasing pipe length increases pressure drop. This can be offset by increasing the pipe diameter.

I take this open topic to make a query related to fuel pressure. I have original fuel ramp feed system, in series. not parallel. Install a fuel pressure regulator on the fuel line return, and also install a pressure gauge at the entrance to the ramps. (Fuel filter outlet). By setting the desired fuel pressure in the regulator (return) to 3 kg / cm2. I notice that the fuel inlet pressure is 3.5 Kg / cm2. There is an approximate difference of 0.5 kg / cm2 between the inlet pressure and the outlet pressure. What would be the correct parameter to take into account when establishing the pressure. The measurement at the entrance to the rails or at the exit. (return). Thank you.
