vacum line info
I've got an 86 F-150 Super Cab, 300, w/4-spedd overdrive manual transmission. The factory engine went out, due to stopped up radiator, at 249,000 miles. I replaced it with a long block from a local parts store, and did not double check the torque on the connecting arms. 20,000 miles later, the arm disconnected from the crank and punched a nice hole in the side of the block. Due to work commitments, and family plans, I was not able to replace the engine myself. I paid a backyard body smasher, to replace the engine. He did a fairly decent job, it runs, and gets me around, but the vacum lines are all messed up. I cannot seem to find anything that has a vacum diagram so I can route the new lines where they are supposed to go. My chilton is no help, and I can't find a shop manual for an 86 model.
Any help would be appreciated.

Your requested information isn't going to come easy. I have a '79 and after 8 months, I finally have a very clear and afirmed plumbing diagram. I assume you can't find the diagram on the hood or near the radiator support? Check out the VECI label on your valve cover. There's a three, maybe four, letter code on the lower right (- I think- that references the Ford diagram you need). You can try the dealer, your local library, or manuals like Chilton's or Haynes'. If you still have no luck, there's two more ideas - go to an emission inspection station, some of them may have a diagram to go by OR monitor used car classifieds (AKA "Auto Trader" here in CA) for your same year/300-6 truck - many sellers are more than willing to let you take a peek under the hood - where you may see a diagram to copy or sketch what you see. Unfortunately, the late feedback carbs and early EFI's are more complicated than basic systems like my '79. Haynes has an emission book that will help explain a lot of the basics, yet -introduce a computer and a simple vacuum gauge won't do a hill a hill of beans. Best wishes. -TETRA

call all of your local auto tune up Professionals and ask them if they use the "alldata" system. When you find one, ask them to print out a diagram for you. You will need the calibration code for the truck. (should find it on a sticker on the front edge of the valve cover.) If you absolutely can't find one locally, check alldata's web site. They should point you to one that is close. If the shop wants a couple of bucks, pay it. It is cheap compared to the cost of the alldata system. "The Dyno Place" here in town will print it for free for me, but I wouldn't want to ask them unless there is no other option. I don't like to use up my favors. Herman
