Default fuel line for zex kit?

can someone who knows about the zex nitrous kit tell me which fuel line i need to tap into for the kit? or better yet give me a picture? i tapped into one line but when i turned the key forward it squirted a bunch of gas into my intake, so im assuming i had the wrong line. also which wire for the throttle position sensor? i think ive got it but not sure. man its a hassle when u buy something used and u get no instructions just a mess of wires and hoses!

I dont want to get you confused, but the zex kit dosent really "tap" into a fuel line you have to use the 2 black hoses provided, what the 2 hoses do is they attach to your fuel pressure regulator and intake plenum (sp?) and raise the fuel pressure when the nitrous is engaged, I dont know to me it sounds like you have a diffrent kit? Just trying to help let me know whats up.

the guy who sold it to me told me to "put a "t" connector in one of the fuel lines and run it to the box". so thats what ive been trying to do.

Could you post a link to the manual? I've looked on the site (and will again after this post) but couldn't find the manual on their site. Installation instructions but not the manual. It could've just been an oversite.

man just got back from work ok, I got confused, you dont need to "T" tap you gotta use the hoses that were supposed to come with the kit, take one of the hoses and attach it to the fuel pressure regulator its on the passenger side of the car its looks like a little UFO, you'll see a small rubber hose connected to the fuel pressure reg, and the other side of the hose connects to the intake plenum, take that hose off, now with one of the supplied hoses attach it to the fuel pressure reg. now take the other end and attach it to the zex contol unit connect it to the side that says "regulator" dont forget to use the hose clamps that were supposed to be supplied with the kit if you dont have any buy some, now that the intake plenum is open you gotta take the other hose connect it to that then connect it to the zex box that says "intake" as for that your done, please use hose clamps I have heard so many people say the hoses have blown off while driving thats one thing you dont want to happen...never.

okay so what youre basically ssaying is i need to find where the intake manifold attaches to the fuel pressure regulator, and instead of allowing the line to travel from the regulator straight to the plenum, im gonna make it so the control box is in between.

instead of regulator -> plenum, itll go regulator -> control box -> plenum. am i understanding this right?

man thanks for the help! hopefully this time i wont spray fuel into my intake as soon as i turn the key on! (stupid guy who told me how to hook it up the 1st time )
