well i will be converting to non oem fuel rails,
first question, i figured i would ask before i hooked battery up, got a gas can and turned the keyto verify. which of the stock lines going to the intake is the feed line.is it the bigger one or smaller one?
second question. the small module on the passenger side of the intake.... that currently has the vacuum line going into it...do i need to keep this or not? i heard it isn't required to be hooked up.
also the vacuum hose that comes out of it goes to a y vacuum fitting. wtf are those lines for...can i just eliminate that $hit. i don't have HVAC system in the car anymore.
thanks alot for the feedback guys...in advance of course

if memory serves me correct the larger one is the feeder and the smaller is return
also the module is for the evap canister mines unhooked and gone of my car
it also has a vac line going to the fuel lines as well as the TB.
now the vac lines that goes into the y fittin might be the ones for the HVAC system
not sure on the 96's
is this the stuff you talking about

Re: for those that have converted to fuel rails...couple of questions
what is it like on your car. i understand that the small line, being the thrid line for the fuel sustem goes into that module, i am just going to disconnect it from under the car and cap it off.
hmm i am running the monoblade, and i don't recall if i have a vacuum line running into the t.b. lol!!! how pathetic! let me run and take a look.......brb........ok, no lines to the throttle body, i didn't think there were.
back to the white y fitting for the vacuum lines. actually one line comes out of the harness lead into the trans tunnel, the second one heads into the wire harness that goes toward the battery.
where is our charcoal cannister in our cars is it under the battery?
thanks

yeah it wont hurt to pull the canister and check valve if you have no HVAC system. but this y-fitting your talking about going into the tranny tunnel is got me wondering where it could go to.?

also of topic....do you think i really need to keep the vented lines to the opti? hell unvented optis do just fine, and the car is driven alot, but mostly in good weather. the more crap i can do away with the better

thanks alot for the links!!!!!!!! they rock!
Re: for those that have converted to fuel rails...couple of questions
try to track that thang down as far as you can.
mine came from the check valve 1 to the inside of car 1 to the vac canister below car by the horns and the 3rd one went into the harness and came out and hooked up to the intake right by the one for the FPR
