2nd hand lcr fuel pump or new a3 fuel pump????

[smokiedee]

hi i've got a feeling my fuel pump is dying even if it's not i'll feel better changing it as cars just ticked over 160k. can i use a leon cupra r fuel pump with my 3 bar fpr or would i also need to change that to 4bar? this is going on my stage 2 agu ko3s a3. or should i just get a new bosch unit for an a3

and id be getting new in both cases.
