Im trying to gather all the original equipment for my 8/68. Im seeing that some came with a smog pump. Were these just on the CA and Federal emissions vehicles, or were they standard on all built from 1968-3/69? Thanks in advance for the replies!

....if they all had smog pumps starting then, why do both of the 60031 heads I have , have no ports for the air rail to plug into? They are not plugged either, they are just not drilled at all. Seems like there may have been no smog pump or air injection from 69 to ? Am I missing something, is it just the CA 40s that had the emissions stuff this early?

@lcwizard had a 68 FJ55 with a air pump. My 9/67 FJ40 did not have any sign of a air pump when I bought it in 74. It is a 68 model with the changes for 68. Curious if the previous page you posted show a listing for just a belt. I do not believe the air pump was on all Land Cruisers in the US market from 9/69 on. When I use to take my 68 thru emissions they never looked for a air pump.

Take Note of My Book Above , The Land Cruiser F Engine's Air Pump Belt's Application / Introduction 6709-6901 , then
NO Air Pump Belt Again Till 7209-Later ,
So I interpret That as Between 6902-7208 A USA Spec FJ40 & FJ55 Did Not have / come with Air Pumps
Is This a possible Explanation ?

Did ALL Smog / Air Pumps Use / have a Air Injection rail & ports on / in the cylinder head itself ?
or
Was there a Early F Engine version that used a single reed type valve or entered the intake or carb / air cleaner box some how ?
The Correct Facts to this Question would suggest the answer to a Air Pump itself ......

Interesting your diagram shows a hose connecting to the air cleaner. I have not seen the second fitting on a one barrel paper element air cleaner. The over fitting is for the positive crankcase ventilation system. It provided filtered air for what was being drawn out of the crankcase thru the PCV valve then into the intake manifold.
Take Note of SST #'s A & H

Does The Presence of 2 Service ports on top of this 1967 Air cleaner Box shed any light ?
( Note : there is only 1 kind / option of air kleaner box in the 1967 parts cataloger )
Take Note part # F (hose)
is that the 2nd hose U refer to ?

My 3/1969 also has this Vacuum Switching Valve and NO air pump at all. And I know it never had one from purchase. Perhaps Toyota really did not need them with a VSV and transistorized drive of it. ? Then in 1972 emissions may have gotten tighter as they do ? Just a guess.
