Undercarriage line?

[Padre Prince]

Installing a zex kit and wondering how everyone ran the line to the bottle? As of right now the control box is sitting just in front of the fuse box with the line running through the frame to the wheel well, then along the bottom to the tank. My concern is that the line may be too close to the exhaust. I ran it through the brake line loop and then back to the spare tire area. It runs about 2 inches above the exhaust. I just want to see or hear how others are doing this. Thanks

i ran mine through the inside of the car, under the door sills, behind the glove box, and out through the big plug on the right side where the wiring harness goes.

I ran mine under the car to the spare tire well

i ran it right down the driver side of the car then carried it over to the brake lines going to the rear and zip tied it to them and threw the tire well to and over the rear axel up in their, it was hard to get it over all the stuff in the rear cus it was so tight in their, then drilled a hole and used a rubber garmet to protec the line from rubbing on the sharp body edge were i drilled, mine is in the spare tire area, no one knows i have nitrous except the big red switch on the dash, i love to have it their lol freaks people that dont know much about cars, they think im going to blow my motor up or brake their necks like in the movies , stupid fast and the furious movies !!!!!!!!

Thanks for the info Guys. I am mainly interested in where the line was routed starting right before the axle. I ran mine below it and as such am thinking that it might be too close to the exhaust which would heat the line and cause problems with pressure. I was reluctant to have the line go over the axle cause it travels up and I didn't want to pinch the line somehow. 05Silverhemimag if you have a picture of the rear part of the line over the axle that would be super. Anyone else for that matter!!!

Thanks - Bryan

Bryan,

I route most of the installs I do on the outside. One thing you'll want to be careful about is the braided line can act as sand paper and wear holes into rubber hoses, electrical wire shielding etc. with engine vibration. So make sure you route it away from them or if they do overlap without being secured, slice a rubber hose and wrap the braided line with it. Last thing you need is a wire arcing across the braided line rupturing it.

I try to route all of our installs through the inside of the car. The lines seem to reach better this way and offers a much cleaner hidden install. The key is to make sure the area you route the hose will not rub against anything. In areas there is wiring I make sure the wiring is in a wire loom and if the hose is going to be upagainst it I coat the line as well. Coming through the firewal I use rubber gromets to seal the hose and hkeep the firewall from cutting into the hose.
Routing it outside the car is fine. Just make sure it is not up agaisnt any moving suspension parts and driveline. Make sure it is not low to where it can catch on something while driving. Also make sure it is not where it will be crushed if you drag the car in a parking lot or use a floor jack on the car.

I routed mine inside, down passenger side. I found a grommet under heater core and brought line through firewall there and snuck it up under the cowl, nearly impossible to find unless you know where to look for it. I also mount solenoids under cowl for more of a stealth appearance.
