Hello.

Im interested to change my original 123d fuel pump to better one. I think some of you guys have done that upgrade?

To the point :D so which fuel pump CP4.2 or CP3 is going to fit n47 engine and does it fit perfectly(no modification needed to do actually fuel pump?)
Am i correct that cp4.2 Fp "full name" is CR/CP4S2/L70/40 ?

And what other mods is needed to do? Do i need to get 335d fuel rail? Cut it and weld it?

Sorry for bad english :)
