Please i need help with my nitrous install

[98MACH1R]

Hey guys i have a 98 GT and im putting on a zex dry kit, now the directions say for the two rubber hoses, for one to go to the fuel pressure regulator and the other hose to go to the intake. Im so lost and have been searching for a couple of days. I dont know if i should t -off anything or what. If you have pics that would help so much

Thanks stangnet

just T into an existing vacuum line that is coming right off of the intake.

can i ask why your using a dry kit? and why does it need vacuum for a dry kit?

 

[98MACH1R]

i like using dry so i dont have to worry about puddling issues, i have first hand expierence that back fires will blow an intake. but do you have a pic where you can show me this because i have a vacume on the intake with just a cap over it not being use, could i just put it on that? and what about the fuel pressure vacume line also? thanks for the reply

If you can't install the nitrous kit yourself, you need to have a professional install it, before you ruin your engine.

You better have bigger injectors/fuel rails and high flow fuel pump for that kit, or your going to get lean spikes like crazy.

Thanks man for the heads up but i have installed nitrous before but never a zex unit and never a dry system, i have done many other installs of h/c/i trans swaps, i am very mech inclined, i just need this help with this, btw i have 24`s aftermarket rails and a 255 pump with colder plugs thanks for the help tho.

what about the fuel pressure vacume line also? thanks for the reply

a fuel pressure vacuum line

 

[98MACH1R]

yea, i mean like i dont know if i have to tee into it or replace it

 

[Stan Weiss]

yea, I mean like I don't know how one line can have both pressure and vacuum at the same time.

 

[98MACH1R]

anyone else?

 

[Saleen4971]

if it needs vacuum, then give it manifodl vacuum. if it need fuel pressure (which it should only need for a safety switch) then you have to put a T fitting into teh fuel rails

that sounds nothing like the zex wet kit i installed a few weeks back.

its cause its a dry kit, thanks guys for the reply, im gonna try and get it done today, if you guys have any other things to put in that would be great and pics are always welcome

did you every get it going. the vacuum line is supposed to go from the nitrous regulator to a T fitting with a special vacuum jet inside that i guess only allows vacuum to go into the hose and not pressure from theh nitrous go out to the intake. then there is a hose from the T fitting to the fuel regulator or fuel rail sensor on a 4.6. that is what i take from it. i am not sure though as the 4.6 has a returnless fuel system. this is why i am asking the same question.

Did you not get instructions...no pics? That sucks...
The FP switch they are referring to is likely the piece on the driver's side fuel rail.
