Where have you guys ran your lines? Is it easier to drill and go under the car or stay inside the car and go through firewall? If through firewall where at?

 

I ran mine inside the car between the plastic molding and the door jam. Then it goes up under the dash(just remove the panel on the underside of the dash and through an existing grommet in the firewall right behind the PCM. You just remove the PCM and there is a HUGE rubber grommet that you just have to enlarge the hole. I chose to run it in the car just to keep it protected and away from the heat of the exhaust when you bring the line up.

Same way I did mine as well.. Cant even see it.

I ran mine through the grommets under the rear seats. My bottle is behind the seat as well.
