I need your help!
Anyone that can send me a picture of their 84 f150 with the 302 2bbl would be really helpful right about now...I need to run new vacuum lines but most of the original are split going other places or capped off. (top end without the breather attached)
There is a map below the hood but its all confusing to me...
I need to get this truck running by the end of the week...dad is taking his car back and told me I need to get this on the road.
PAH-LEEZZZ HELP ME OUT HERE!!!!
Thanks.

Had you put the topic in the title I would have looked at this earlier.
Please put the topic in thread titles
You didn't list enough info abou the truck.
The best is to post the claibration code or engine Identification code from the valve cover sticker.
It should be 3 letters in the very bottom left hand corner of the decal.
There are so many different calibration codes (that change hose routing) a poerson has to know what the code is and for that they need this info:
Model Truck
Engine Type
Axle ratio
Transmission type
Operating local (49 state or calif)
Once you get me that info......I'll help

The way to understand these diagrams is simple, each hose has a connection, each connection goes to a part, you will notice what some of the parts are, traced them out first, then each one check to make sure the hoses are good and tight, and relace any that you think could be bad or leaking, hoses that are old and dirty, oiled soak and split should be replaced. You want to make sure everything is snug and tight. Don't glue the ends to the parts or put any wire or clamp on them. They are desiged to be tight but not easy to pull off, snug is what you want.
Be patient and trace every hose to its proper place, if you don't know where something should go, ask here and we'll help you locate it.

Ok not to rob your thread but I also need help with this, could someone explain what the letters mean on the diagram? For example what is a A/CL CVM or a VCV.

Here is a great Automotive Dictionary.
http://vvvvvv.odessa.ua/
If you put in the Smog part Abreviation, such as VRDV in the search box, it will tell you what it means.
If you look at your Vac Diagram, it will show sketches of the parts, in the relative area where the part is located, Front back, left right, etc... Look around the engine in the relative area shown on the diagram until you find the part.
If you can't find the part, it is a good chance that it may have been removed.
Good luck!

That APD number is useless.That's a decal number
Do you also have a yellow or white sticker on the valve cover ,,that has a UPC code on it ?
You can find some of those abbrevations defined here.
