sources. One small spark to the outer braid of the line will destroy the Teflon inner-liner. Secure the line carefully, zip ties work best here. Before connecting the line to the bottle, purge the line of all possible debris by carefully blowingcompressed air through the line for several seconds. Connect the line to the bottle valve and tighten securely.

CAUTION: An experienced technician familiar with the use and handling of high-pressure cryogenic gases should install this system. If you have any doubt about your skills this system should be taken to a qualified shop for installation. If you have decided to dothe install yourself please read and understand all of these instructions before you start. Some of these instructions may or may not apply to your vehicle, if you have any questions please call our tech department 940767-7694 9:00A.M. -4:00P.M. CST. Before starting, disconnect the negative terminal on the battery. If you have any questions about your particular car consult a shop manual.

Figure A
Mounting the Nitrous/Fuel Management System & Nozzle: 1. The nitrous/fuel discharge nozzle should be mounted in the air duct that connects the air cleaner to thethrottle body. 2. Drill a ¼ inch hole between the MAS Air Meter and the throttle body in the plastic/rubber ducting. 3. Thread the nozzle into this hole until all threads are covered. Be sure the nozzle discharges toward the engine. 4. Using the horsepower jetting chart select the desired jets. Insert the jets into the nozzle fittings being sure to insert the correct nitrous and fuel jets intothe correct fittings. Note: The larger jet # always goes in the fitting marked “Nitrous” 5. After installing the jets into the nozzle using the supplied red (Fuel) and blue (nitrous) hoses, connect the Nitrous/ Fuel Management System to the nozzle, paying attention to connect the Nitrous outlet port to the fitting labeled Nitrous on the nozzle and the Fuel outlet port to the fitting labeled Fuel 6.Using a backup wrench, connect the previously cleaned supply line to the Nitrous Inlet port and tighten securely. NOTE: ALL HOSES MUST BE INSTALLED WITH A BACKUP WRENCH ON SOLENOIDS! Plumbing the Fuel 1. Locate the factory supply line connecting the fuel filter to the EFI fuel rail. This line must be cut and a Tee inserted to supply fuel to the nitrous system. Use extreme caution; this linecontains flammable fuel under high pressure. Carefully cut this line and insert the Tee fitting. Use the supplied clamps to secure a leak free installation.

Mounting the Bottle & Routing the Supply Line 1. Assemble the nut and nipple on the bottle as shown in Figure “A”. The nitrous bottle should be mounted outside the passenger compartment; if this is not possible an external venting blow down tubeis a necessity (NX PN 11708 & 11709). A minimum of 4-5/16, grade 5, bolts with washers must be used for a safe installation. The bottle should be mounted as shown in Figure “A”. Check beneath floor for obstructions such as fuel tank, fuel lines, electrical wiring, etc before drilling holes. Have the nitrous bottle filled with “NY-TROUS +” nitrous oxide. A local speed shop or a welding supply shopcan usually handle this.

2.

To route the supply line drill a ¾ hole beneath the valve discharge port. Before beginning the routing procedure place tape over both ends of the line to prevent debris from entering the line during the installation process.. Now route the line beneath the car being sure to avoid all exhaust, suspension and other moving parts. Following the factory fuel line is...
