I've been looking at different setups of fuel systems. My car is a s5 t2 swap so I'm replacing pretty much all the stock fuel stuff. Would it be better to put a y splitter fuel distributor and run fuel to both rails then output to another y splitter that then puts it into a fpr? or would it be easier to just input the fuel into the primary, then have it go to the secondary then onward to the fpr and just not use any y splitters. currently i'm only going to be using the stock size injectors. but im trying to set it up so that if later on if i wanted to add larger injectors to get more power i wont have to redo the fuel system then to get the necesarry amount of fuel. i hope that makes sense.

 

I´ve done like this:

I think it´s better to feed the rails parallel, and instead of using a Y-connection
after the rails use a FPR with 2 inlet ports.
