installing the nozzle in the cylinder head make sure the cylinder you are working on is at TOP
DEAD CENTER (check with service manual for any questions) then place a rag or rags in the
port to prevent debris from entering the cylinder (if the rags are coated with grease they will
get almost all the fillings out of the port). Carefully start a 1/16-npt tap (NOT INCLUDED IN
THE SYSTEM) in the hole, making sure you are square to the hole (being careful not to cross
thread the tap). Once the tap has started add a couple of drops of a light lubricant. Turn the tap
about 2 full turns then go back about 1/3 of a turn, this will keep the tap from getting stuck on
the removed material. Repeat the process until approximately 1/4” of the tap is exposed inside
the port. Remove the tap and test fit a nozzle, when threading the nozzle in by hand it should
stop approximately two turns from having the start of the threads flush with the surface of the
port. If the nozzle will not go in far enough repeat the tapping until the nozzle is at the correct
depth. Once the correct depth is achieved, remove the rags) and blow out the port with
compressed air. Put clean rags back in the port and move on to the next port, repeating the
procedure.
4. Select the horsepower increase you desire by viewing the chart found in the jet bag. Select
the indicated jets and insert the jets into the nozzle, the nozzle is marked “Nitrous”& “Fuel”
for your convenience. Connect the stainless braided lines, RED FOR FUEL, BLUE FOR
NITROUS, over the jets and to the nozzle and route the lines to the solenoids. Using the
provided brackets, mount the solenoid in a central location that allows the proper routing of
the braided lines.
5. Do not use Teflon tape on any nitrous system component!!! Use Supplied NX Red Thread
Sealer only!!! No sealer is required on AN flare fittings; sealer is required on pipe style
threads.

SECTION 3: PLUMBING THE FUEL SYSTEM
This is the most important section involved in the system installation. In all cases an adequate fuel
supply must be furnished to the fuel pump. On a carbureted street system a stock petcock is usually
adequate. On a carbureted competition system a Pingle style dual outlet petcock is required. On all fuel
injected applications, you must tap the fuel tank for your fuel supply to the included electric pump. (Do
not “T” off of the high pressure line leading to the fuel injectors, use PN15724P to tap your fuel
tank)
This system is designed to be used with a Nitrous Express fuel pump (PN 15005P). No fuel pressure
regulator is required, however: if a high volume aftermarket pump is used, a regulator is required. A fuel
filter is included with the Nitrous Express fuel pump.
1. Carbureted street systems are furnished with a “T” fitting that may be used to splice into the fuel line
supplying the carburetor. Route a rubber fuel line from this “T” fitting or fuel outlet to the inlet side of
