A "smog pump" is an air pump that is driven by the belts on the front of the engine usually mounted on the lower passenger side. It pumps air into the exhaust so the chemicals left over after the engine combusts the gasoline/air mixture will break down further in the catalytic converter.

The vacuum can (looks like a coffee can) is simply a vacuum reservoir. Basically an empty space that doesn't leak air. This can be connected to a vacuum distribution node (a block of plastic where a bunch of vacuum hoses connect, usually top passenger side of engine). The vacuum distribution node will need to connect to a vacuum source, usually the carburetor.

The Evap canister is for the gas fumes inside the fuel tank. Gasoline evaporates at room temperature. These gasses build up pressure inside the fuel tank. To ensure these gasses don't escape into the atmosphere, they have designed a way to "suck off" these gasses and feed them to the engine where they are burned like the rest of the fuel. So there is a vacuum line that runs from the fuel tank all the way to the engine compartment. There it goes through the evap cansiter, into another vacuum hose, and eventually into the engine via the carburetor.

Here's some pictures for you to look at:

You should have a vacuum-routing diagram on the panel just ahead of the radiator on the passenger's side. If you can post a picture of that we can help. But, this page in the stickies provides a decoder: Ford Truck Enthusiasts Forums - View Single Post - Vacuum Diagram Acronyms

Did you just buy this truck without a smog?

on edit: No he didn't, see next post and................... well, never mind....

I did have an '85 E150. The computer was on the passenger side in the van, about as big as a fat laptop.

There were 4 (iirc) solenoid gizmos on the valve cover, and the miles of plastic tubing came and went in that area.

Good luck on this

Vacuum diagram for 1986 F150 300-I6



The original smog systems that came on your truck weren't too complicated. They are/were controlled and monitored by a simple computer in the cab, near the gas pedal, with a few sensors and electric solenoids out in the engine bay.

Are the original smog parts still present in the truck? Or did your dad maybe remove them? Yes, pics of your engine bay would help us.

About all that I can tell from that picture is that you do have the diagram. But it does look very similar to the one Galendor posted. So, we can use his if you can't get a better pic.

I've never had FTE say "low memory" so I suspect it is something to do with your mobile device. Are you clicking the yellow "postcard" icon, above, and choosing Browse Your Device?

Anyway, hospital? Hope it isn't too bad.
