Here is a pic to help you see how to tap into the fuel test port on the fuel rail. Notice that one of the red arrows is pointing to the FPSS, put another gauge adapter before the FPSS and put the electric sender there. That way it is inline with the 'noid and FPSS.

Alrite, thanks for clearing that up for me

Oh an I measured the nozzle distance from the MAf and its about 3.75 inches, I thought it should be at least 6 inches away. Why do the recommend that?

So that it wont damage the MAF as much. If its too close the pressure of the nitrous could break the sensor. I dont think you have much choice in the placement of the nozzle because you dont have an intake tube, just a filter right on the throttle body.

What jet sizes is it telling you to use?

Jet sizes dont matter for engine size. 4 cyl, V6, V8 etc, doesnt matter, a 75 shot is a 75 shot.

Completely inaccurate! Jet sizing does matter! Call NX, NOS, ZEX tech support and ask them if the V6 has the same jetting as an LS1. I can pretty much guarantee you will be laughed at!

For the OP, don't spray without fuel. Your nozzle is meant to mix fuel and nitrous. If the fuel isn't present, the nitrous will back flow in to the fuel straw and place alot of unneeded stress and wear on your fuel solenoid. If you're really itching to spray that bad, I have a spare NOS dry nozzle and braided line I could give you a really good deal on.

just cap off the fuel part of the nozzle on a wet nozzle and it would work fine dry as well instead of going to the fuel solenoid.

Re: I think I'm ready, you tell me.

Here is what NOS sent me for jet sizes:

HP Nitrous/Fuel

40 34/18
50 37/22
60 39/24
70 41/26
80 43/28
100 46/30
125 52/33
150 61/38

Those are a tad on the rich side, but those are what I use and they worked fine.

As far as I know ZEX uses the same style jets as NOS.
