Looks good man. Now ??? Are you feeding the FPR first or feeding the back of 1 fuel rail, then out to the FPR?

Feeding the back of the rail first. Last thing in line is the FPR, then returns to tank.

Ok and no issues so far? This is ultimately the way I am going to run it. Alot of guys say to feed both rails then Y it back into the FPR then tank

I have my fuel system the same way as smokeshow, no problems.
For the fuel rails, I had a shop weld some tabs to fuel rails and they fit perfect, they have no play in them what so ever.

Sweet!! Looks good, not sure why you even tried to fit that FPR back in the location that it was originally in though...is there even room? Lol
I know how to fix my turbo...there's another turbo on this Maroon RCSB 4WD that is not being used to it's potential, just grab that one, no one will miss it!

I had mine originally like the way your talking about, feeding both rails and than Y'ed back into the FPR and back to the tank. Never had any issues with it like that either but Jake said it makes no difference.

What rails are those

Not sure if the L92 intake is the same as the TBSS one, but instead of grinding the posts you can space them up and space the injector...

What's holding the rails down in this set up??? Is there a bracket that attches to the bolts on the side???

I have the rails tapped for the screws going into the sides of the rail, the screws going into the tops acts like a set screw. No brackets what so ever.

Corey, they are professional products.
