that boost leak is bright red and sitting on top of the motor, just put a damn procharger hat on that thing and it'll pick up power

Am I the only one that noticed the factory fuel rails?

So thats a turbo and a eaton with factory fuel rails? Heck I got yelled at for not having my axle tubs welded before the shop took picks. lol

I thought 98% of after market rails were -8. I hope it works but I just changed mine out with the rest of the fuel system. I am still returnless though.
