Directly on the fuel rail on the passenger side of the motor. Just unscrew the cap, remove the shrader valve inside, and then screw your fuel line on and you are set!!
hemi450, just in case you didnt know, you are the man. thanks
HAHA...No problem. Now go finish the install and let us know how it feels with the juice!!

hahaha, hey matt, i think you should quote that, make it big and bold and put it in your signature!! you are tha man!!....just dont quote ME on that. lol
What does the line look like. I found a metal hose with a port on it, but i thought my fuel line was rubber. and when i do find it, how do i remove the shrader valve
Well i want to sell my 24s now and im going to ahead and mess with the engine.. I want to know how many mods do i need to do so I can spray?
The test port is on the fuel rail lke hemi450hp said, not fuel hose. The rail is an aluminum pipe.

On the passenger side just above and to the front of the 2nd plug coil from the front.

The valve looks like the valve in your tires.

You can use a small eyeglass screwdriver or use a tire valve stem removal tool to get it out.

Don't lose it, if you ever get rid of the nos, you'll need to put it and the cap back.

Also, I suggest removing the gas cap to relieve the pressure before you remove it and place a wrag over it as you do to catch the gas spray.
ok so that was the hose that i was looking at. i took the plastic cap off and the inside does look similar to a tire valve. The problem is that the hose for the fuel line to the nos wouldnt fit the fuel port. Do I need to buy an adapter? And on the inside of the port i see a pin. Not anything that can be unscrewed with a small screwdriver.

If the fuel line supplied in the nitrous kit doesnt fit, then you will need to either buy a new braided line with the right fitting on the end, or get an adapter like you said. I would probably buy a new braided line though...1 less leak to worry about.
The valve that i found has threads on the inside of the valve. The nos line connection needs to hook up to something with threads on the outside. Is the valve you guys used have threads on the inside as well? I just want to make sure i am looking at the right one. Thanks again

You are looking at the wrong one then. Here is a pic of mine just to show you what we are talking about. It is on the passenger side just to the right of the 2nd coil pack to the front. I have a silver cap on mine, but yours should be just a black plastic cap...
