I have an S3 fuel pump here i removed from my old Stage 2 plus S3, want to sell it but have no documentation of uprated internals when i bought the car even though it was on Stage 2 plus and made 363bhp

Can i strip the pump down and be able to check? Suppose to be Autotech will there be markings? or the size of parts etc

Thanks
