Ok, so I'm finally down to mapping out my fuel system for my S400/LQ4 setup in my Typhoon. I have aftermarket -8 rails, and my fuel system has a -8 feed, -6 return.

What would be the recommended FPR for the boosted LS motor and my setup.

Also, I know it's a no-no to mount it on the firewall. Can you mount it directly on the rails?

here is my setup:




Any help would be greatly appreciated.

Thanks,

 

You can use any regulator that is boost referenced to raise fuel pressure 1 to 1 with boost and has the required ports for your -6 return. You can mount it right to the rail with a 3/8 male to male pipe fitting or run a short line to it away from the engine.

 

Cool thank you. They won't turn you away at the track with it mounted that way?
