Factory emissions equipment on 1986 k10
 

All, would like a general list of the factory required emissions equipment (non-CA) on an '86 k10 with manual transmission. I know cats were required, but how about an air pump? What controls were used on the factory carb? Other equipment?

Thanks!

Page 39 of the 1986 Chevrolet Truck info kit from the GM Heritage Center has a chart showing all of the various emissions equipment for both federal & California emissions for each of the available engines.

It looks like all of the gas engines used air pumps that year.

Not all '86 trucks with cats. My K2500 GMC didn't have them due to heavy duty emissions. Engine code M. It did have A.I.R. System on it though with 2 pumps. It was set up for leaded fuel if it could be found.
