Fuel tank, high pressure rails and fuel lines need cleaning. You need a new fuel pressure regulator and a fuel pressure sensor, injectors need to be tested/replaced and a new fuel filter.
As for the CP3 conversion there are guides on how to do it on youtube, however the car won't run without re calibration.

I got full fuel system with cp3 pump so will have everything from fuel filter so will need to clean the lines from fuel filter to tank and the tank itself do you have any recommendations how to ?Fuel tank, high pressure rails and fuel lines need cleaning.

yes I did look how to do on YouTube there is not many videos that I can find it but will keep looking yes I do know will need some calibration will get somebody to come and do this
For the tank you can use soapy water to clean it, wipe it clean and keep flushing it until the water is clear. Do the same for the fuel rail and lines and blow them out with compressed air. Then run in the ultrasonic.
As your car is a CCWA you will need a new lift pump also.

What do you mean by new lift pump?
is that the pump in the fuel tank ?For the tank you can use soapy water to clean it, wipe it clean and keep flushing it until the water is clear. Do the same for the fuel rail and lines and blow them out with compressed air. Then run in the ultrasonic.

Your car has an additional electric pump. Which feeds the high pressure pump.
In tank pump -> Electric Pump -> High Pressure Pump

do you know what it looks like or any part numbers ?Your car has an additional electric pump. Which feeds the high pressure pump.

I went from cp4 to cp3. Bobby Singh is your man.
did you went same way as my or you just decide to upgrade ?I went from cp4 to cp3. Bobby Singh is your man.
My car kept going into limp when on full throttle. I didn't want to chance it with the cp4 throwing swarf into my fuel lines and possibly damaging my injectors so opted for the cp3. My car was mapped by Bobby a few years ago and the cp4 pump was on the limit. So went for the cp3 and the drivability is loads better plus I got more bhp and torque with the cp3.
i wish i did it earlier now i got loads of more problems now but hopefully all be good i got all fuel system from cp3 coming this week from fuel filter include injectors. did you do it your self or Bobby Singh did it ?My car kept going into limp when on full throttle.

Bobby fitted the pump etc, it needed to be mapped in so made sense for him to do it all.
