So I have a 79 Ford F100 with a 302 from a Lincoln Mark 7. It wouldn't pass smog until I put in a new catalytic converter. Henceward, the pump seized, got replacement, but it turns out the bolt that attaches to is missing. Found a replacement bolt that goes in perfectly to the hole designed for the alternator. The smog pump bolt hole is only a half inch. Is that right? In the picture, the upper arrow shows the bolt hole for the alternator. The lower arrow points to the only hole the pump goes into. And it's stripped. When I googled smog pump brackets for my truck, there was a photo of those inserts with another hole with thread inside it. I don't know if to assume the bolt hole is the same size as the top hole. And how do I determine what size to get? Measure it? I believe I have to drill a larger hole. But it only goes a half inch in, and those inserts are tapered. Sorry for the spider writing. Sure I'll clarify. Thx.
top hole for the alternator. Lower hole, the only one that accomodates the smog pump.
The guy I got this truck from said it was an 85 Lincoln, so your diagrams are right on. Can I get the diagram for the smog system for the 79 Ford F100?
Thanks to both for the diagrams. I see that I'm missing piece 9b289 in the latter set of diagrams. What is it/what does it do and how can I get this part? Thx.

9B289 is the air by pass valve, but the one used on a 1985 Mark VII 302 is completely different than the type used on a F100/150 302.
Did the 302 come from a '85 Mark VII LSC? If so, this is the same HiPo 302 used in Mustang's. The non LSC's used the 'plain jane' 302.
I inn you have a point. the quote about California engine swaps follows. It's the last entry that has me confused. But even before that, I should be able to get my hands on stuck a part as mentioned above. What is it called? Here's the California dmv: Skip to Main Content

Home Industry Engine Change Guidelines
Engine Change Guidelines
Engine changes continue to present problems and challenges to car owners and technicians. Our recommendation is to rebuild and reinstall the original engine, transmission, and emission control configuration.
When rebuilding an engine, it must be rebuilt to the original equipment specifications. However, if you do decide to change the engine, these guidelines must be observed to ensure that the vehicle will be eligible for smog certification or registration.
Remember, these are guidelines for performing engine changes - not certification procedures. All exhaust emission controlled vehicles with engine changes must be inspected by an official Referee station and must have a Bureau of Automotive Repair (BAR) Referee label affixed to the doorpost.
Remember also, state and federal anti-tampering laws generally prohibit any modification to the vehicle's original emission control system configuration as certified by the manufacturer. And, Section 3362.1 of the California Code of Regulations prohibits any engine change that degrades the effectiveness of a vehicle's emission control system.
California Certification
A federal Environmental Protection Agency (EPA) certified (federal or 49-state) engine cannot be used in a vehicle that was originally certified for California.
Certification Standards
Make sure the engine and emission control configuration on exhaust-controlled vehicles are certified to the year of the vehicle or newer, and to the same or a more stringent new vehicle certification standard.
Classification
Don't mix engine and vehicle classifications which will degrade the emissions certification standards. For example, a heavy-duty engine cannot be installed in a light-duty exhaust-controlled chassis even if they have the same displacement. Non-emissions controlled power plants such as industrial or off-road-use-only engines may not be placed in any exhaust-controlled vehicle.
Computer Controls
If a computer-controlled engine is installed in a non-computerized vehicle, the "CHECK ENGINE" light, the Original Equipment Manufacturer (OEM) diagnostic link, and all sensors, switches, and wiring harnesses needed to make the system fully functional must also be installed.
Emission Control Configuration
Mixing and matching emission control system components could cause problems and is generally not allowed. Engine and emission control systems must be in an engine-chassis configuration certified by the California Air Resources Board (ARB) or U.S. Environmental Protection Agency (EPA). The engine must meet or exceed the requirements for the year and class of vehicle in which it is installed.
Emission Warranty
Voiding the vehicle manufacturer's emission warranty is not allowed.
Engine Modifications
No internal or external engine modifications (cams, pistons, intakes, etc.) may be performed unless the parts are ARB-exempted or EPA-certified for use in the installed engine. Refer to ARB's Aftermarket Parts Database of Executive Orders to search for exempted aftermarket parts.
Original Equipment
The installed engine and host chassis must retain all of their original emission control equipment. Diesel-to-gasoline conversions must have all gasoline engine and chassis emission control systems installed (such as fillpipe restrictor, catalytic converter, and evaporative emission system).
I believe it's a hipo because the firing order is hipo. I only have the check valve on there aND there are two components missing per the 85 diagram...9b289 and 9f491. AND that hose that extends from the bottom of that thermactor,...what is that hooked up to?? Thx.

I only have the check valve (there are two different types, see both 9A487's in pic) on there and there are two components missing per the 85 diagram: 9B289 and 9F491 = exhaust air supply valve.
AND that hose that extends from the bottom of that thermactor what is that hooked up to?? Thx.
The system is called Thermactor, but there's no part by that name.
I only see one hose leading from the smog pump (9A486 in pic), is that what you're calling the Thermactor?
Here's the '85 (same as 1984/86) pic again, so you don't have to scroll up.
Yes, there is only one hose leading from the pump, but after that, there's one component, and then further on there's what I think is called a thermactor. It bifurcates the one hose, one leading to the back of the engine. The one coming from underneath the 'thermactor' ,... where does that go?

Look at post 12 again. There's no part of the Thermactor Emission system that's called Thermactor.
I've been looking this T/E crap up in parts catalogs since 1966, so I know what the various parts are called.
T/E was introduced in CA vehicles (Passenger Cars, F100/Bronco/Econoline) in 1966.
Oh the joy of living in CA and going thru a smog test on 1976 and newer vehicles.
Sometimes I have to be told twice. It's a bypass valve, ok. Just one more thing please. What is the part listed as 9f491, and where does the bottom hose lead to? Many thanks.
