8. Now is the time for bending the hard lines to connect the Fogger nozzles to their respective distribution blocks. A tube-bending tool, available under NOS P/N 15991NOS, is required for this work. Use all the fittings provided and be aware that NOS has color-coded the nitrous lines so that "red" is for fuel and "blue" represents nitrous. Nitrous nozzle feed lines should be bent and plumbed so that they are in line with each distribution block.

9. Re-install the intake manifold, using all hardware that was retained during its removal. Be sure to use a new intake manifold gasket. Re-attach all lines, electronics and any other parts that were removed or disconnected during the intake manifold removal process.





10. The next step is to tap into the fuse box for an ignition-activated power source for the toggle switch that is used to "arm" the nitrous system. This switch can be installed at a location on the dash that is convenient to the driver. Activating this switch puts the nitrous system into a "standby" mode. The system itself won't actually function until the engine is at wide-open throttle (WOT). This condition is confirmed by a WOT micro-switch that is installed on the throttle body.

11. The purge valve (a momentary button) can be installed at this time. This valve is activated to expel or purge the nitrous lines prior to use for more consistent performance. This procedure is good insurance that the nitrous lines are free of air and/or gaseous nitrous that could hinder or compromise performance. Be sure that the purge line is aimed away from the motor. A good idea is to have the purge line aimed so that it will shoot up and over the windshield.

12. The last installation step is to plumb an additional source of fuel to the fuel solenoid. Fortunately, the Skyline had an extra NPT tap on the O.E. fuel rail; this was used as a fuel source.
