8. Once you have completed all of the before steps, it is now time to install the NXL rail. Just gently
place the rail and injectors over the NXL nozzles and line them up. Press evenly and firmly until all
injectors are fully seated in the nozzles. Then screw in the allen head screws through the fuel rail
bracket and into the NXL fuel rail. You may finish tightening the rail mounting studs on the intake.
9. You may now install the nitrous and fuel lines from the rail to the nozzles. When installing start from
front to back on the rail to the nozzles with the exception of the first one. If you will notice that in the
third picture the front NXL nozzle on both sides of the intake, attatches to the third set of outlets. Then
starting with the second one, they go from front to back, this is due to the tight radius of the hose.
10. Before wiring up the NXL system you will need to put the fuel crossover together. First get the two
Aeroquip fittings supplied in the kit, lubricate the inside of the hose ends, then slip the fittings into the
hose. Be sure to butt the hose up against the coupler of the fitting. Then tighten the -AN nuts onto the
NXL fuel rails and your fuel setup is complete
