I was wondering what the correct setup is for plumbing aftermarket fuel rails. I have mine setup, but I know they are not correct. Can anyone chime in & help me out!? Thanks!

I have my regulator after the rail, instead of before, like yours.

It'll run fine the way you have it now, but ideally you'd connect from the outlet of the fuel filter to the rear of the passenger side fuel rail and plug off the port on the regulator that you currently have the feed line coming into. As you have it setup now if you start making a lot of power the injector at the dead end of the system (passenger rear) can be starved for fuel.

The best way is to run your feed line to a Y block, than the two lines to each fuel rail. Then plum the two fuel rails into the regulator, and run a return line back to the tank.

I have mine coming off the second filter(post pump) to the back of the driver side rail, then crossing over(well under the intake) then exiting out the back of the passenger side rail to the FPR then back to the tank...that ensures adequate fuel to all of the injectors. In a really high HP car a yblock setup would be more ideal, but ill never hit that kinda HP for my street car.

This is the best way. I will run mine into the fuel rails then to the regulator. One thing is the mounting of your FPR. It's against NHRA rules to have it on the firewall and I would follow that for general safety.

Thanks for all the feedback, anyone running a similar setup with pics to share? I'm trying to keep this as clean as possible! Thanks!
