i went to mess with my car some more and i was plugging in the hoses. so i was like ok cool not that hard, so i turn my car on..itruns ok..but i didnt push the peddle down or anythin just idle, so i put my
hand around the tubes checking for leaks..no major leaks, so i put my finger on the nitrous output nozzle, and instead of air coming out its sucking in air...its
supposed to blow out air right? i flipped the switch to on, same thing, i havent tapped my intake yet bc i want to make sure about i used the right hoses. when i drove i went WOT but nothing changed. yes i flipped the switch, and yes the zex box is works, i can hear a click, and we tapped the correct wire, the only thing we're not 100% on is the hoses....so now what? i dunno, what do u think? any pics of the correct hose placement ?remember i have a 99 accord v6 thanks

you should have a small vaccuum hose that connects from your intake manifold to the top of your fuel pressure regulator. That is the hose that you need to interface. Just imagine that you are going to hook the NMU in series with the intake manifold and the fuel pressure regulator. That covers the vaccuum hose connections.

The nitrous connections are made with the steel braided hoses. You should have a "nitrous in" and a "nozzle" port. The "nitrous in" port runs back to your bottle. The "nozzle" port goes to your intake pipe.

You should not get any air blowing out unless there is nitrous in the tank. The only thing that should be sucking air in is the hose that comes from the intake manifold.

I may be misunderstanding your problem though... You might try calling ZEX if you get really stuck. I had pretty good experience with their thech line.

Okay...take everything you have heard about the ZEX kit and throw it out the door. Here is what I found when I opened up one of those Barney boxes, you can believe me or not, and definately more than welcomed to open your own gay-ass-purple-barney box.

When you open the block, there is what appears to be a large solenoid(compared to the NOS powershot anyways.) Attached to it is a distribution connector that routes out into three directions. One is for the "regulator" slot, one for the "intake" slot, and yes, the third for the "n2o output". So the reason why you might have felt some sucking when you put your finger over the nitrous output is because there should be sucking. When you use your nitrous, the solenoid opens up, allowing nitrous to spray out of the nitrous output to your nozzle, through the intake slot to the intake manifold so that the MAP sensor reads the extra pressure, through the regulator to the fuel regulator. When the fuel regulator gets sprayed with the nitrous, the fuel return orifice get's covered, so that your car's fuel pressure increases to compensate for the nitrous.

Anyways, that's a brief summary of the ZEX kit. Hope it's been of help to someone.

yes, that sounds right. Basically it seems to me that there are 3 ports on that solenoid becasue when the barney box is at rest, 2 of those ports act as a throughput and when the solenoid gets activated it bypasses the first port to switch to the other one. When it switches to the other port it creates more vacuum to the FPR and thats what increases the fuel pressure. Thats why my AEM FPR blew up... :) Atleast that is how I understand it anyway...

Stupid question but did you fill the bottle and open the valve before you attempted to inject ??

lol coop, if you would have parked your car a little further up, that water fountain sprinkler thing in the background would have looked like a cloud of nitrous that you just purged ;)

Nothing is gonna come out it there isn't any pressure in the bottle... If you heard the solinoid in the box activate the have the wiring rgt. The vacuum hoses are easy too... Just fill the bottle and see if it ejects out. It is gonna be -130 degrees (somewhere around there) so dont hold the line in your bare hand wear a thick leather glove. Then see if it ejects. Make sure you have the proper jets in.
