UPDATE: I bought a new fuel filter (just because im already messing around with it) and rotated it so that the return was 12 o'clock.

D runs is a thermal switch I think and runs from the dampner on air cleaner that controls the exhaust coming in from the tube
E is a thermal switch the comes from CTO then to EGR
F is the dampner that open to let exhaust in during start up. Cant tell but mine has another dampner on air cleaner that block off intake to filter when engine is off-
both air clearner lines T together then tie into port B on mine
My dizzy advance is on manifold off the brake booster line. I think sometimes it is hooked into C.
COuld use A maybe?
Get a Vacuum pump/gauge it will help a lot
ported vacuum= 0 at idle and increases with throttle. ports located above throttle pplate
Manifold Vacuum= should be 18-20 at idle and falls with throttle- located below throttle plate
that all for now.
check out Advneture under the hood- esp for air cleaner operation
The way that my Jeep is now:
A- Goes to a canister of some sort that is connected immediately after the air pump.
B- Goes to the "Purge Signal" port on what I think is the vacuum canister.
C- Goes to the dizzy advance.
Everything else is not connected to anything.
EGR is capped
Does the EGR do anything except improve emissions?
