Good piece of information, I may have went with them had I known that. Not that there is anything wrong with Felpro, they just didn't come with the bolts which you could easily spin $40 alone getting from GM.
One other thing I want to add about the O-Ring coming off the Inlet hose going into the Fuel Rail, be real careful and try and center the pipe in when installing the line. I put it on and mine leaked terrible because I must have nicked it good putting it in and it practically cut the O-ring in half. ITS REAL EASY TO DING THAT ORING INSTALLING IT. Its a tight fit, thats why everyone loses it when pulling the pipe out because it catches and shoots off once you pull that tube out. Take your time, its time consuming having to go back and replace it not to mention its an expensive O-ring and impossible to find on a sunday with the dealer is closed. I tried O-Riellys, Advance, and Autozone and they all told me they couldn't help me.
