I can see how alot of people can run the nitrous feed line through the interior of the car but I'm leery of that plus I already have alot of other wires going through the grommet.
For those who ran the line under the car what / how did you attach it to the underside of the car? Where did you exactly run it? And how did you bring it into the engine bay?

 

zip-strip it to the underside, theres lots of crap under there to tie it to. then run it under the firewall and bring it up the firewall/fenderwell, just watch out for headers and other stuff like that.

 

I ran it pretty much with the fuel/brake lines underneath the car and secured the line with lots of cable ties.

 

I have -6AN nitrous, -6AN fuel supply and -6AN fuel return lines bundled to the stock fuel lines using nylon wire ties. At the front of the car, the nitrous line goes up behind the plastic fender liner, and into the engine compartment behind the headlight, where my purge and solenoids are located.

Injuneer and gtp.. where are your bottles mounted? Mines in the spare tire compartment I'm trying to figure out if I'll have enough line to do this with my hsw kit (16')

 

ya you deffinitley will. it depends where your line is under the hood(if you have it running from the passenger side then run it to the radiator support and wrap it all the way to somewhere on the drivers side for your solenoid, it might be tight, you will have more than enough to play around tho and figure out what will work best.

 

That is where my bottle is, I ran out of line. I ended up having another 4 foot line made up by Harris and I bought a union fitting to mate the two lines together.

 

Mine is in the hatch well, on the driver's side.
