2.5 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.
2.6 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 solenoid 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.
2.6.1 Preparing To Mount Your Solenoids
1. Locate the EFI solenoid bracket, solenoid “tee”, and solenoid mounting screws.
2. This solenoid bracket can be modified (bent, twisted and/or cut) to allow for easier installation in areas
with minimal clearance . Please look at the photo on the next page of a typical solenoid mounting
location, and adapt your bracket according to the needs of your particular application.
2.6.2 Nitrous Solenoids Mounting
1. 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 of the solenoid.
2. Install nitrous filter fitting (Blue fitting 4AN X 1/8 NPT) using liquid Teflon, in the inlet port of the
nitrous solenoid.
3. Install one of the 1/8 NPT male sides of solenoid “tee”, using liquid Teflon, on the outlet port of the
nitrous solenoid. The female port of solenoid “tee” should be facing outward.
4. 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 second solenoid so that it parallels the first.
5. Install the 3AN x 1/8 NPT (blue straight fitting) into the outlet port of second nitrous solenoid.
6. Install one end of the 1/8 NPT male x 1/8 NPT male nipple fitting, using liquid Teflon, into nitrous
pressure regulator inlet port.
7. Loosely thread nitrous pressure regulator/nipple assembly into 1/8 NPT female port on solenoid “tee”.
8. Using liquid Teflon, install 1/8 NPT x 3/16” barb fitting into nitrous pressure regulator.
i. Remove nitrous solenoid/regulator assembly from vise.
ii. Attach EFI solenoid bracket to the bottom of the solenoids.
ii. Verify the desired mounting location for the solenoid/regulator assembly.
9. Install solenoid/regulator assembly in desired location.
10. Tighten nitrous regulator until barb fitting points towards the vehicle’s fuel pressure regulator.
11. Leave all wiring loose for electrical systems installation.
12. Connect main nitrous feed line to inlet fitting (4AN x 1/8 NPT nitrous filter fitting) of the first nitrous
solenoid.
