wow... thats weird... well you can either hack something together i suppose, OR you could buy something like this:
http://www.americanmuscle.com/nx-fue...er-9904gt.html

just for reference here's the link to american muscles install video:
http://www.youtube.com/watch?v=xRhYw...ayer_embedded#


you can skip to the very end to see how they connect it. they show their schrader valve at 9:10. its on the driver side for them it looks like. they also have coil packs which leads me to believe they are installing on an older 98 model. what's really odd is that i have an 03 with a schrader valve, and u do not?

edit: if you skip to ~ 9:45 they show a picture of a fuel fitting for a 96 cobra. its a T-fitting. this might also be a cheaper option instead of the above 60$ adapter...

interesting... OP where did u buy the kit? did u buy it used? AM.com also states that it includes a "fuel T" which im assuming is an optional adapter to splice into the fuel line if you dont have a schrader valve.

the AM.com kit doesnt make any mension of the adapter block though.
trueblue, where did u buy your kit?

My kit is the 75-175hp kit (I think p/n 82217). I looked at purchasing it from one of about 4 different places. I think the 75-125hp kit may not have had this adapter. At least I seem to recall not seeing it in the picture of the components included.

ZEX sells this adapter seperately, so anyone could get one if needed. It was an easy and effective method of hooking the supply line to the rail.

Yea Zeroo, it came with a "T Fitting" that can splice into the 1/4 inch fuel line running inbetween the fuelrails but its VERY tough to get back there, I have no idea how I'd manage that. Either way I dont think I'm going to install this kit this year the car is going to sleep in 4 weeks anyways. But it'll be nice to know in the spring.

It is the 75-125 kit, I bought it new off ebay, but its the same as American Muscle sells. TrueBlue, at first glance I dont understand how this adapter sets up, I'm looking at the picture can you explain? Is it fuel in on the bottom and fuel out on the top and then you can thread in a feedline to your nitrous box on the side? Does it mount clean somewhere with the 2 bolts provided?

that block is meant to go onto the driver side fuel rail, there's a little black box for the fuel rail pressure sensor. you take that off, install the adapter block, then reinstall the FRPS. this would provide what looks like 2 threaded holes, you can then run one of the adapters off of that NPT threaded hole to the fuel line for the nitrous kit.

you can see in the picture i have posted up its on the right side, there's a nice little place for it (doesnt show the black box)
you can see in your 2nd picture, the black FRPS...

^^^^ Exactly right.
It is a simple method of hooking the fuel line to the fuel rail.
