Fuel Pressure Regulator?

[tomsdubs]

Tried searching but can't understand what's the deal with mine. I have a PH2 172 2003, I read that the pressure reg was moved from the rail but I still have the take off hose from my manifold? Should this be capped off? The previous owner has just left a piece of hose dangling connected to the manifold. Starting to wonder now why my car struggled with emissions at MOT, just doing my dephaser and there are bodges everywhere!

Sounds like the hose that goes to the acoustic valve on ph2 as reg is in the tank/sender unit, if it is block it or refit it
