20. Run the other end of the braided nitrous line up to the engine-compartment area and mount it to the nitrous solenoid. Rather than tie-wrapping it to the car frame and nearby hardware, we took a little extra time to snake the line through the framerails all the way up to the front of the car. Because our braided line is within the framerails, the chances of it being snagged or damaged by nearby moving parts are greatly reduced. Notice the tape over the end of the line. This prevented dirt and crud from getting inside the line while we routed it under our not-so-clean '70 Chevelle.
