So was was replacing my valve cover gaskets today and when I was doing the left side a bunch of thin lines, vacuum maybe, lines broke. I got rubber replacement lines because I couldn't find the hard plastic line that were on there before. I think I got everything matched up the way it was but when I turned my trucked and tried to rev it there was a lag before it revved. I am not sure if this is because of the rubber lines or I connected something up wrong. I took pictures of everything I was removing but other stuff broke so i had to do a bit of guessing. Is there a diagram of all these lines that go to the carb and the valve that screws into the thermostat housing?

 

Right in front of the radiator support by the hood latch, there is/was a sticker with all your vacuum lines & components mapped out.

Definitions of all the abbreviations are here - Ford Truck Enthusiasts Forums - View Single Post - Vacuum Diagram Acronyms

If it's missing, or your engine has been swapped, some Chiltons manuals have a lot of the stickers illustrated.

 

Im going to have to get the manual, no sticker for me.

 

Here's a 84 300 six cylinder.

 

Whoops, you said "valve covers" plural so you must have a v8. Here's a 302.

 

Wow! Thank you very much!

 

Good job, Franklin2! I tried to rep you, but could not. Perhaps someone else will.

 

Done, David

 

Hats off to you, Ken! Thank you.
