OUTLINE OF CONSTRUCTION
Theefuel and emission control system of the new 323 4WD model 1s basically the same as that of the prevr-
ous 323 4WD model; however some parts are changed. The changed parts and interchangable parts
are shown betow.

OUTLINE
l Thspressure regulator has two vacuum ports for its two-stage operation. (Refer to page F3-43.)
l The injectors are changed from high-ohmic type to low-ohmic type for improvement of the supply of fuel
during high-speed engine operation.
l To decrease the current in the injectors, an external resistor is equipped and is mounted on the aircleaner
housrng .
