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 the nitrous line end under the hood loose pending installation of nitrous solenoid.
2.5 Solenoid Assembly and Installation
Nitrous Solenoid Assembly
1. Hold the nitrous solenoid securely in a bench vise, being careful not to harm the solenoid or block the inlet or outlet
ports of the solenoid.
2. Install the nitrous filter fitting (4AN x 1/8”NPT Blue Fitting) into the inlet port of the nitrous solenoid using Teflon Paste.
3. Install the nitrous outlet fitting (3AN x 1/8”NPT Blue Fitting) into the outlet port of the nitrous solenoid using Teflon
Paste.
4. Remove the solenoid from the vise and attach a solenoid bracket using the supplied solenoid screws.
5. Find a location in the engine compartment to mount the solenoid, making sure that it is within reach of the feed line
and nitrous plate.
6. Connect the 3AN x 15” 90° blue hose to the outlet port of the nitrous solenoid.
7. Select the nitrous jet you will be using and place this in the “N” fitting of the nitrous plate. Connect the 90° end of
the 3AN hose line to the nozzle with the jet installed.
8. Connect the 4AN nitrous feed line to the inlet port of the nitrous solenoid.
Fuel Solenoid Assembly
1. Hold the fuel solenoid securely in a bench vise, being careful not to harm the solenoid or block the inlet or outlet ports
of the solenoid.
2. Install the fuel inlet fitting (4AN x 1/8”NPT Red Fitting) into the inlet port of the fuel solenoid using Teflon Paste. Do
not tighten this fitting at this time. Once you have found a mounting location for the fuel solenoid, you will then tighten
this fitting so you can clock it to the best angle for connecting the fuel feed line.
3. Install the fuel outlet fitting (3AN x 1/8”NPT Red Fitting) into the outlet port of the fuel solenoid using Teflon Paste.
4. Remove the solenoid from the vise and attach the remaining solenoid bracket using the supplied solenoid screws.
5. Find a location in the engine compartment to mount the solenoid, making sure that it is within reach of the fuel feed
line and nitrous plate.
6. Select the corresponding fuel jet and place in the red fitting of the nitrous plate. Connect the 3AN x 15” 90° red fuel
hose from the outlet fitting of the fuel solenoid to the fitting on the nitrous plate with the jet installed.
