2.4 Nitrous Feed Line Mounting
1. Determine the route your main nitrous feed line will follow. Ensure the path does not route the nitrous feed line
too close to the exhaust system, suspension, electrical lines/components or tires.
2. Attach nitrous supply line to bottle.
3. Feed nitrous line along proposed route.
4. Secure nitrous supply line to underside of vehicle.
Note: Stainless steel covering of the main nitrous feed line is very abrasive. Shield painted components or
sensitive system components like electrical, fuel lines, brake lines or suspension components to prevent them
from contacting main feed line. Rubber hose can be slid over and retained as a chafe guard.
5. Leave nitrous line loose pending installation of nitrous solenoid.
2.5 Solenoid Mounting
Use the following procedures to install the Performer nitrous solenoids.
Note: Remember to use
Teflon paste only
on pipe threads. Do not use Teflon tape.
Hint: Placement of the solenoid is often limited by the lack of possible mounting locations in the engine
compartment. However, if possible, observe the following suggestions:
Solenoid Safety Information
1. Keep solenoids and lines away from exhaust components.
2. Trial fit the solenoids with all lines attached to ensure a proper fit.
3. Solenoids may be mounted sideways or upside-down, if necessary.
2.5.1 Nitrous Solenoids Mounting
1. Locate the EFI solenoid bracket, solenoids, inlet fitting, outlet fitting, plug, solenoid tee, and solenoid
mounting screws.
2. Hold one of the nitrous solenoids securely (like in a bench vise) being careful not to harm the solenoid
or block the inlet or outlet port of the solenoid.
3. Install the nitrous filter fitting (Blue fitting 4AN X 1/8 NPT), using liquid Teflon paste, in the inlet port of
the nitrous solenoid.
4. Install one of the 1/8 NPT male sides of the solenoid tee, using liquid Teflon, on the outlet port of the
nitrous solenoid. The female port of the solenoid tee should be facing outward.
5. Install the remaining 1/8 NPT male end of the solenoid tee, using liquid Teflon, into the inlet port of the
second nitrous solenoid. Rotate the second solenoid so that it parallels the first.
6. Install the 3AN X 1/8 NPT (blue straight fitting) into the outlet port of the second nitrous solenoid.
7. Install one end of the 1/8”NPT male x 1/8”NPT male nipple fitting, using liquid Teflon paste, into the
nitrous pressure regulator inlet port which is the port on the end.
8. Loosely thread the nitrous pressure regulator/nipple assembly into the 1/8”NPT female port on the
solenoid “Tee”.
9. Using liquid Teflon paste, install the 1/8”NPT x 3/16” barb fitting into the side of the nitrous pressure
regulator.
10. Remove the assembly from the vise and mount the solenoid bracket to the solenoids.
11. Install the solenoid/regulator assembly in your desired location. Tighten the nitrous regulator until the
barb fitting points towards the vehicle’s fuel pressure regulator.
12. Leave all wiring loose for electrical systems installation.
13. Connect the main nitrous feed line to the inlet fitting (4AN X 1/8 NPT nitrous filter fitting) of the first
nitrous solenoid.
