Ls1 fuel rail on ls4 intake
« on: Jul 31, 2015, 06:42 PM »
I recently had an accident and damaged the fuel rail on my gxp and im having a hard time finding a replacement thats not way over priced.
I think i read somewhere that the ls1 rail will bolt right on but im having trouble finding that thread or any other info on it.
As far as I can tell the part is almost identical and would just like a conformation on it before i go ahead and buy it. any help is much appreiciated  :smiley:

With modification I'm sure it would fit but short answer is no it won't. I'm not sure if other rails would mount right up but ours is definitely a little different.

Ah o well. Thanks for the reply tho.
I did find one finally for 150 it was the last one they had too. it seems like they are in short supply tho, but im still curious if any others would fit on ours.
They seem to range in price from 200 - 400+ kinda steep considering the GTO one was 115
