Going to call Perrin today about this but im hoping its a simple problem. This weekend I installed my Perrin fuel rails and everything went fine. When I start the car it seems to idle fine but when I give it gas all hell breaks lose. The check engine light will pop up and then the engine light will start flashing. It also seemed to lag when giving it gas during this time (lack of fuel??). After this happened I immediatly turned it off and check all the lines again to make sure everything connected. Looks to be no leaks at all and everything is connected correctly. I also primed the system and followed Perrins instructions fully. I am using the stock FPR and the vacuum line is also connected properly. Somebody please help since I am not even going to attempt to drive it until I get it corrected.

Thanks

What other mods do you have? It's a little late now but IMO rails are a waste!

I went ahead and upped the rails cause the factory rail kept leaking on the passenger side where the rail on the intake manifold meet to the rail. I would try to tighten and replace the couplers but it would keep leaking. I was done messing with them and sought out this solution. Here is my current mod list egine wise.....

-HKS headers w/ Up pipe
-Perrin FMIC
-Perrin catch can
-STI oil cooler
-4" Bellmouth DP
-EVC 5
-Apexi TT
-Ti turboback exhaust
-Perrin Turbo Inlet and elbow
-Worx BOV
-Blitz Intake
-Perrin fuel rails

Did you replace all the o-rings and seals. Mine have a tiny leak from a pinched o-ring, and oil up the rings when you install them. Just an Idea

Did it since Perrin recommended it, rings were perfect.....
