4.5 From VCV for Distributor Ventilation (passenger side) Line (x) to distributor cap via "T" connection with line (z) Line (y) to air cleaner cover on the passenger side Line (z) to distributor cap Line (s) to gas filter (manifold vacuum fitting) 4.6 From HAC I believe that all HAC routing as described here is unchanged from stock. HAC port (a) to carb port C HAC port (b) to carb HAC Slow Port HAC port (c) to carb port A HAC port (d) to "T" fitting: o One leg of the "T" goes the distributor HAC Advance Port o Other leg of the "T" goes to the Gas Filter via a check valve 4.7 From Gas Filter There are three ports on the Gas Filter but only 2 are used after desmogging.
All three are vacuum sources so it doesn't matter which lines connect to which port. The first line connects to VCV for Distributor Ventilation port (s) The second line connects to HAC port (d) via a "T" fitting and check valve The third line is unused and should be plugged 4.8 From Air Cleaner 4.8.1 Air Cleaner Cover Three ports on the air cleaner cover, driver side: o One port to VCV for EVAP port (x) o Second port to carb Choke Opener o Third port is unused and should be capped One port on the air cleaner cover, passenger side:
o To VCV for Distributor Ventilation port (y) 4.8.2 From HIC The HIC (Hot Idle Compensator) is the white valve on the bottom of the air cleaner on the passenger side. Routing from the HIC is unchanged from stock. HIC port (a) to HAI diaphragm on air cleaner snorkel HIC port (b) to "T" fitting above PCV valve. Version 2 / 01-May-2011 Page 16 of 24
