well how many hoses are there again?

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

I am really sorry but we have no vacuum line diagrams for this truck.

code 82 on a 94 OBD 1 system is the thermactor air bybass valve most likely .Or the electro drive fan circuit is failing or thesbs circuit if you have a superchargerIts most likely your AB valve is cloged this will be a hard part to find i can give you a # of a place that sells this stuff after market LCM IS THE NAME you would need to call them and they would send you a magizine for free for your vehicle and you would need to take it from there but the parts are avaible just not at the dealer

code 44 is thermactor air injection system inop

For more research google the above phrase.

Vacuum diagrams for a 1978 Ford F150 are included in this shop manual https://www.fordshopmanual.com/ford-truck-shop-manuals/1978-ford-truck-shop-manual-pdf-download/

Most likey a bad thermactor valve is damaged and is allowing hot air to enter the pump causing it to overheat and fail. Need a lazer heat gun to see how hot it is getting.

Follow this link. It may help you narrow down the cause of your problem.

Had the same problem. Likely the fusible links. Get a Haynes manual with wiring diagram in the back (should be around $15 or so at an auto parts store). I also had to replace the air intake duct and several components of the thermactor air system. One other thought is that the new alternator is not putting out a charge, you might want to check that if you believe everything else is okay. I once replaced an alternator and the new alternator was defective. --Mark http://www.marksatterfield.com
