Ok, So I got the upper intake manifold back on, it was a pain in the *** to get everything back on but I think I've finally got everything back on, however, now I've got some questions about vacuum lines:

Instead of running the lines to bungs on the intercooler piping, am I allowed to run it to the nipples right after the throttle body on the UIM?

Do I really need to run a line to the purge control solenoid valve? Also, what does the check valve, PCV valve, and gas filter look like? Is the gas filter a plastic looking thing?

If I've got an aftermarket Fuel Pressure Regulator I don't need to run the vacuum lines to it do I?

Which spark plugs are the leading and which are trailing? Are the ones on top leading? Also, which lines go on which spark plugs? The outer lines go on trailing?

Also, for the Fuel Atomization line, which one is that? Is that the giant nipple near the oil injection vacuum lines?

Thanks a lot for the help!!!

Dude, this sounds like a clusterfuck in the making.

Do you not have the FSM? Pretty much all your questions are answered there.

there are no lines that run directly to the intercooler piping. there are however lines that run to the y-pipe, and yes, those lines must be connected at their normal positions on the y-pipe

if you dont know what these things look like your in for a big hurting. but i will try to explain.

the purge control valve controls the addition of fumes from the charcoal canister into the intake manifold. if you live in a state with emissions tests connect otherwise you can vent it if you dont mind the smell of gas all the time

the check valve, PCV valve and gas filter are all plastic looking things, but.......
the check valves are tapered on each end and round in the middle
the PCV valve looks kinda like a T
the gas filter also looks like a T but is a little larger than the PCV valve with a smaller cap and is only used on the vacuum line to the MAP sensor

fuel pressure regulators require vacuum lines regardless of OEM or aftermarket

look at your coils, the coil with 2 leads in the leading coil, the top is rotor 1 and the bottom is rotor 2. the coils with only 1 lead each are the trailing coils the one nearest the front is rotor 1 and the one closest to the firewall is rotor 2
the bottom plugs are leading, the top are trailing. mark your wires with a sharpie before you install them so you dont have to check every time

next time do a search before you ask all these questions or atleast look at the FSM before you waist everyones time by asking questions you could easily find the answers to yourself
