Hi folks I've searched all over the webs with no good result and all of my service manuals were passed on years ago. I have a 1972 MkIV and have managed to forget how the hoses were hooked up the old petrified ones I usually use for reference were discarded. Hoping someone here was smarter than me and still has a service manual. Its a '72 Mk IV, 460 engine of course, 49 state emissions. Thanks ! Be safe all.
Leadslead has 1973 manuals for his CP and Galaxie, and they should be very close, if not the same; if he can lay his hands on them, I'll take a look, see if there's a diagram or two.
Pollution, err "emissions" controls were evolving rapidly in the years from the Nixon administration until wide use of computerized fuel injection. I'm pretty sure that by '73 EGR and vacuum retard were added but remain hopeful those charts will be useful. Thanks, I'll stay tuned.
