I recently bought a Zex dry kit from a friend of mine. I was planning on going for a wet kit, but since he was practically giving it away ($150 used for 3 months) I decided to buy it.

As I'm reading the installation instructions I see that I need to tap into the "vacum fitting on the engine's fuel pressure regulator". Does anyone have a pic or description of where this is located? Would this be one of the tubes coming off of the intake?

Thanks

 

I know it is a mean thing to say, but you need to read the FAQ's. There are a bunch of pics of nitrous installs that show you exactly where everything goes.

 

I checked the FAQ's before I posted and did not find anything that showed me where it was. I just re-read them and still cannot find anything. If I overlooked something I apologize.

This is the closest thing I could find in the stickies:



I cannot tell from this picture exactly what hose they tapped into. Any additional help would be appreciated.

 

 

See...You found it. The hose on the bottom of the FPR pulls off, and hooks up to your T-valve, and the other line from the T-valve goes back on. It's easy. There are more pics in the stickies that show people's nitrous installs in depth, and show exactly how it is set up. Just make sure to secure the hoses
so they don't interfere with the throttle. A friend of mine had a problem where the hose got in the way of the throttle returning to rest position, and he hit a curb because he couldn't stop his car.

 

Thanks for the help on that Jime.

I have one more question about the install. I need to know where exactly to connect the "intake" tube coming out of the Nitrous Management Unit. The kit says to "connect this hose to an unused vacuum fitting coming off the intake manifold plenum". Can I just tap this into one of the tubes coming out of the intake, or is there another spot I am supposed to use?

I THOUROUGHLY searched through the FAQ's and install pic threads for a third time and have not found any of this info.

Thanks for the help (again)

Use one of the gold vaccuum hardlines under the throttle body...there is certainly one with a rubber end cap you can remove and plug in the hose from the NMU to that one...then you are ready to wire it up and feed the spray line and run it...spray safely.
