I just got a 1986 d100 from North Carolina, I live in PA. The smog pump was completely unhooked when I got the truck (lines cut, etc). I'm pretty sure I need the smog pump to pass emissions up here and could not find any diagrams or pictures on where the lines go and how to hook them up, just how to take it off. So if anyone could provide pictures and or details on how it hooks up that would be great. It's a /6 by the way.

 

I’m not at home by my service manual at the moment but when I get home tonight I’ll come back in and post all the air pump pages for you if you’d like?

 

That would be great. The Haynes Manual told me nothing before the pump.

 

Do they still do testing on vehicles that old???

 

Yep all the way back to 75, Highest gas tax on the nation, and right in the middle of the rust belt. Gotta love PA

 

From the 87 Service Manual. 86 should be similar.

 

Sorry, I'm kinda new at dealing with 80's emissions stuff but if I'm reading that diagram right a tube comes off the upper cat, where around the spot where the upstream o2 sensor would be on a second-gen which is routed into the pump which blows the air into the EGR looking port on the side of the engine.

 

Here are the pages I promised, If you need any of the removal, repair, etc. let me know and I’ll check in before I crash out for the night

and even though I have a 318, if you need to see what tubes and hoses go where I can take picture during the daylight for comparison.

 

I think that will be all I need that great. Challenge will now be trying to find the line that runs from the upper cat to the pump as mines cut off.
Prob will have to make one.
Thanks, guys
