Nitrous Oxide - Running main line through Vette LS2 Im ready to loose it!

Ok Guys anyone here run the main line through the grommit on the LS2 Vette???? Im having a hell of a time. I even bought a electricians fish.
I saw the picture below and am going crazy. Can anyone help???
I know Robert56 has done this a 1000 times but hes hard to get a hold of.
Maybe Dave, Or some other pros. Not a big fan of the directions I got for this kit. Its seems to me that there is another grommet or another part of the same grommit in the way. Another issue there seems to be 10lbs of shit in this 5lb bag.
Im ready to loose it! Please help:bang:
Mike:confused:

If it is like the C5 the gromet has a thick rubber ring inside and can be pulled out. It has a cut in it and is a little over a half inch thick. It can be removed from the insde of the car and you will find it is much easier to work on then.
When I ran my line I drilled a seperate hole next to the gromet and ran the feed line seperate since I already added a bunch of wires to the original. Hope that helps you out, I know you can fit some big stuff through once you remove the ring.

Thanks! Thats what I was looking for!:D
