So I bought a 78 f150 for a project and need some help with where what hoses should be plugged in where.. Tried looking at diagrams but they just confuse the hell out of me. It's got a 79 460 in it. The only hose I'm sure is right is the one from the distributor. All the lines were hooked up how you see them when I got the truck. Any help would be greatly appreciated.

All those hoses in the 2nd pic don't do anything. Looks like you have manifold vacuum from the manifold hooked up to manifold vacuum from the carb. Take those off and plug it all up.

The vacuum tree in the 3rd pic is feeding the PCV, the a/c doors, and the power brake booster, it looks to me. Those are fine, although, to really have it correct, you should move the PCV line to that center port on the front of the carb (that is currently hooked to the other vacuum tree in pic #2). This will make it so that vapors from the crankcase are distributed to all the cylinders, not just #4 and #7 as you have it routed now.

 

That's the information I was looking for. Thanks!
