    hrfunsail, not sure if your rig is federal or california. here is figure 41-44 from the mitchell emission manual. you would have to pick which one you need. Fig 41 and 42 are related to calibration number 8-97-RO. Fig 43 is cal number 8-66U-RO, and fig 44 is for the F350. Cal # 8-66U-RO is teh california truck and the 8-97-RO is federal. Hope these help. You will have to email and email address i cannot post the pics to large.

I need the vacuum diagram for 1986 ford truck with a300 6cil


Short of a Haynes or Chilton repair manual for pickups covering your year's truck, I don't know if you could find a vacuum diagram easily on the internet. However a google search might give you a strand of hope. That was about the year that ford (and all of them to be sure, to some extent or another) went crazy with vacuum controlled emissions and operations. As soon as they grudgingly accepted fuel injection over carburetors as the reality, all those crazy vacuum diagrams disappeared. They met emission regulations through better computer management operations. Sigh, I'm still reliving the nightmare of electronically controlled carburetors (feedback carburetors, as your ford is called-works real good when it is working good) via my 1987 sentra with two solenoids in the carburetor for fuel-air mixture control- now I'm looking for a replacement carburetor. You would not believe the virtual array of vacuum lines on my sentra. They even included a long stack of metal tubes across the top of the engine, lol.

Anyway, by now that truck is so old, what do you need beyond the brake booster hose, the vacuum advance to the distributor, if you have a MAP sensor equipped, that is a straight manifold tap, and then a tap for the egr valve, maybe controlled by a thermal switching valve-you know, when the coolant is hot, the valve switches air, or vacuum really, to the egr valve. Your charcoal canister would have, I think, a manifold vacuum hose. I might be missing a few, but you might be able to struggle through it. If you have a working smog pump, maybe called an air pump, you will really need a vacuum diagram. There should be several older ford truck enthusiasts forums that you could join. Somebody would surely have it.

Getting a code for smog pump


better check that info again. inspect belt routing diagram and vacuum diagram for thermactor pump and thermactor air system parts being present on your calibration. to my recollection there was no thermactor air used. where would they put all that plumbing?
pump, diverter valve, exhaust check valves, upstream and downstream air tubes? a ford has a label on the radiator support depicting the usage, hose color, and general vicinity in a schematic for ford technicians to identify. there is also a belt routing diagram that depicts the pulleys for the components. you dont have one...right?
you may have a code glossary for older vehicles. get the right manual at the library for free and restart diagnosis. or goto the emissions authorized repair facility and get the question answered after a quick self test

My ''nox'' emissions was to high on smog test?


Usually a high NOx reading on gasoline vehicles is caused by a bad catalytic converter on your exhaust. I would suggest having this checked out before you try the test again. Hope this helps.
