N2O line install route?
N2O line install route? I am installing a TNT Kit and I made up a bottle mount for the spare tire well. How should I run the line to the front, inside the car and up thru the PCM grommet, Or outside the car and along the bottom ?
What are the pro's and con's of each, rules, etc

I ran mine under the carpet and along the inside door trim to the grommet. We had somebody check the rule books about this a few months ago and it's perfectly legal to route the lines throught the cockpit. Make sure you put some wire loom or something around the feed line at the grommet, there are alot of wires under that kick panel that can get chewed up.

I have done mine both ways... reason being i had to get some warranty work done so i had to lose the juice for a week or so, I like the route in the cockpit a lot better than outside. As for the comment about leaks, there wont be a leak inside the car if the install is done right, like someone said up top wrap it in wire loom and you should be alright, when mine was under the car it got worn a little in one spot, but i cought it luckily before i caused serious damage to my main feed line, and it is a lot easier to pull the bottle out do to some extra slack. theres my 2 cents.

I vote for outside the car. If the line justs blows you don't want to be breathing that stuff, It's happened to me and couldn't stop coughing for a few hours. Even though inside is alot easier to do. There was a thread on this before a couple of months ago ( any issues with running lines through interior).The desicion is yours.

I say outsude the car not only because the gases are out of the cabin but I've seen what happens when an N20 line breaks underneath a hood. The unsecured 2 foot section cracked the hood in 2 places and beat the underside of it and the valve covers pretty bad until the bottle ran dry . I wouldn't want that going on in the cockpit while I'm going down the track or even just driving down the street.
