checked the pressure hose to your FPR?
If its a tired pump then an inline pump is not a fix... do you have logs to support the AFR on the dyno graph? need to check requested vs actual... could be the maps actually asking for that AFR...
Its most likely the pump in which case a new one is required but would need to see the AFR logs from VCDS to confirm...

Might be worth taking a trip up to Bill's then as you are just down the road... J13 M5...

Not sure what his schedule is like but I suspect there would be easily time for a road log if nothing else as it will be evident fairly quickly whats going on
May see you tomorrow then...
