The solenoid... Goes from the UIM, thru the solenoid... Thru the catch tank to the charcoal canister. Do I remove it? Or just hook it back up? It's the purge control..



And the vacuum line that runs thru the hard line above the front rotor housing... WTF is that for?



Thanks girls!

That line should hook up to blow by tank that mounts to the lower throttle body, then i runs to the charcole canister back by the diff. There are 3 line that come in at the same place Fuel Pressure line, Return and that line that line. I got rid of that line on mine, I don't know why you couldn't take the hook off. It make make pull/installing the engine a little easier, mine doesn't have that hook.

Your line in red is the second PCV line. It connects before the primary tubo on one end and the nipple on the oil fill neck that points down.



The solenoid I would leave on unless you have a Haltech or something. No performance reason to take it off. If you do take it off you have to decide whether to leave the line hanging ouf of the charcoal canister (therefore venting gas fumes to the atmosphere, gas smell), or plug it (pressure will build up in your gas tank and vent when you go to fill up)

Tyson is correct, https://www.nopistons.com/forums/pub...1047683664.gif I forgot about the oil fill. Mine now runs from the hole of the side of the oil fill to a catchcan and the bottom is capped.
