no your FPR dictates fuel pressure, whilst the higher rated pump provides more flow..........

you can occassionally get a failing FPR that can't cope with a higher rated pump

No,as the fuel pressure regulator regulates the flow that is right for your car that's why you can fit one (fuel pump) without remapping.SJ.

The only advice I would give you is double check all fittings for tightness,it is fuel your dealing with,apart from that you will be fineSJ.
