Are you reading engine ECU or BSI, they look like BSI faults, you need to read engine ECU fault (P-Codes)

Also worth checking fuel pressure when idling and also at around 2500 RPM in live data as you could also have a failing HP fuel pump which can give all these errors

Peugeot always change the pipe to ensure no debris from the old pipe gets into the system. Most people only change the pump with no issues, you maybe able to get a second hand pump they are used on a number of vehicles include the MINI and some BMW's and just change the pump.

I would only fit a Bosch or branded part (Febi, Valeo etc) or second-hand if needed in preference to a unknown Chinese or similar part.

It's a critical part and built to very fine tolerances and if poor quality unit is fitted and fails it may contaminate the fuel system and damage all of the injectors and worst case a failure could result in high pressure fuel leaking from the unit with serious risk of fire etc
