Aftermarket FPR

Is it possible to install an aftermarket fuel pressure regulator with the stock rails? If not, where can I buy new fuel rails for my S5 TII Vert?

This completely depends on what rails you are running. If you have the S4 type with the threaded fitting in the end, replace the FPR with a banjo bolt and install an aftermarket one downstream of that. I think that all turbos had a threaded secondary fuel rail.

Okay, mine doesnt have a threaded fitting in the end, so guess I need a S4 rail then. Are they the same except from the threaded fitting?

I had my friend cut my S5 rails and weld on steel -6 AN weld adapters.

They're not the same, but you can use an S4 on an S5. You just need to get some washers to space it appropriately and probably some longer bolts to hold it on.
