Hose Job question
I am doing the vac hose job and just got the nest installed back in. One question.
There is a vacuum hose that comes off near the FPD and another about 1 inch away on the engine block closer to the ACV. I cannot remember which goes where and the hose drawing is not clear. Anyone know?
I think the one near the FPD goes to Y in the hard tubing of the nest and the engine block goes to the first solenoid nearest the firewall.
Can anyone confirm?

You have this diagram, correct?

There is a nipple underneath the FPD that belongs to the rear rotor's oil injector (pure blue in the diagram). Do not forget about this nipple!
There is another nipple this is pointing diagonally towards the firewall on the LIM pictured below. It's aqua blue in the diagram and dissappears behind 4 prallel vacuume hoses.

Jonski your're a lifesaver!
Jonski,
I have the same diagram. It is not clear to me.
You are correct. There is a vacuum line right under the FPD. That is the the one I am not sure where it goes? I also have a line labelled to go to the solenoid "A" that comes off a fitting in the back of engine block near the passenger side? I am guessing that goes to the nipple on solenoid "A" that face up towards the hood.
I am not sure what you mean by oil injector?
The one your have pictured angling towards the firewall I have connected to the pressure regulator solenoid "A" (orange plug) closest to the firewall. On the nipple facing the fender
I guess it is the Aqua blue lines that I cannot see where it connects to from the solenoid? They both disappear on or near the pressure regulator on the drawing?
Any further wisdom?
Everything else seems to match up okay.

mecman,
It sounds like your FPR (Fuel Pressure Regulator) solenoid is hooked up correctly. Aqua-blue hoses.
There is one oil injector on the front rotor and one on the rear rotor (the one underneath the FPD). They inject oil to lubricate the apex seals (the tips of the rotor). Without these your engine loses lubrication in its combustion chambers. Look closely at the colored diagram. The oil injectors both connect to the metal tubes above the solenoid rack. Those metal tubes are joined together and then connect to the little blue cylinder-shaped thing that solenoids "I" and "J" a connected to.
Klar,
The simplification (a.k.a. emissions removal) removes:
EGR (Exhaust Gas Recirculator) - bleeds exhaust gas into your intake while cruising at highway speeds to redure combustion temps, which makes cleaner emissions. You're '94 will either need an aftermarket ECU or the relay trick to prevent a CEL (Check Engine Light).
ACV (Air Control Valve) - Directs air from the airpump to the pre-catalytic converter and main catalytic converter. Eliminating this insures you will never pass a smog exam.
DT (Double Throttle) - I forget what this does but many people have removed it without consequence. It's the second pair of throttle plates in your UIM.
... and all their associated solenoids.
You can pick and choose what you want to remove. That diagram shows what that guy removed.
