Can the inlet and out of primary /secondary fuel rails be reversed .instead of having the fpr lines go the the rear of the fuel rails (closest to the firewall ) ,I wanna put the lines in front closest to the alternator) Does this affect anything? Thanks

As far as I know, on my S4 anyways, inlet was on the front of the primary rail through the fpd and out the front of the secondary rail through the fpr. And I think that's how all N/A's are, don't know about turbo though, so if it's turbo disregard all this.

In stock form, the TII and NA actually flow in opposite directions. You can route the fuel however you like as long as the FPR is the last thing that the fuel flows through before it returns to the tank.

If you are making a custom system, then you may want to consider a parallel setup. Here is an example:

Thanks 88 na Gxl thanks for your input ,but I have an t2
@ at evil aviator that picture is exactly how my setup is and have been running it that way for a few years .from my understanding of what your saying ,its ok to flip my y connector with my fpr and run it in reverse as long as my fpr is the last thing before retuning to the tank .im just trying to be 100 % sure it's safe before I do it thanks.

And for those wondering why I'm changing my set up is because I've just installed an fd uim and would like to mount the fpr on the front side of the uim

Evil Aviator, when you say opposite directions I think in through the secondary and out through the primary. I'm assuming, instead of front to back, the turbo runs back to front in the rails?

plainandsimpo, yea I figured I shoulda just inserted my foot in my mouth after I posted that. But, besides that, I don't see a reason why you couldn't flip sides.
