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

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.

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

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.
