Cosmo,
I have the Facet EFP on both my 3 and 4 and there will be one on my 6
project. Mounted on the back of the trunk just to the left of the fuel tank
outlet. Regulator mounted on a plate bolted to where the original fuel pump
bolted to the block. Fuel filters before the pump and before the regulator.
4 seasons on the 4 and 2 on the 3 with no fuel delivery problems at all.

EFP only.

I have heard it is best to install the pump closest to the fuel tank or cell
in your case.
