rats nest

You dont have an EGR, thats only on Californian spec, pre-95 cars.  As per my earlier post, make sure you have kept the vac line that goes to the FPR as the diagram above does not show it.

You do need the pressure chamber, so one of your vac lines with a check valve needs to go to it.

so could i connect it to the red hose on the pic the bend near the uim.

I\'d just leave it where it was to start with!

When I stripped out ACV, double throttle and AWS off mine a couple of weeks ago only removed the solenoids and vac pipes that were no longer connected to anything. That left me with two nipples to blank off on the UIM (which I joined together witha short length of vac pipe) and some unused hard pipes in the rats nest.  Job done, no need for confusing diagrams drawn for US cars that didn\'t match my rats nest!

Those three pipes your talking about go straight through the UIM and not inside it., dont use them for the pressure chamber just use any one that is after the throttle body.

you mean the three vertical ones? That\'s the LIM

there\'s a yellow hose on the Y-Pipe that seems to go nowhere (it actually connects to the UIM). connect your pressure chamber check valve to that.
 
use a stanley knife to get difficult hoses off; make a cut along the length of the pipe and gently split it open with an electrician\'s screwdriver. if you break any solenoids keep the nipples, i managed to fix one with some carefully applied Araldite
 
also, the stock FPR connects to a small nipple on the block side of the UIM, via a solenoid. ditch the solenoid and plug it straight in, it\'s the lowest down nipple that sticks out horizontally. it\'s a pain in the arse to get to with the primary fuel rail in place.
