how many vacuum lines are there and where are they?

i know its sounds like a stupid question but i want to check them all. i'm new to the 5.0 engine so i need help.

also, i read once that people plug a line. are they talking about the pipe line that goes to the exhaust pipes?

Here you go....... if your car has the Mass Air (MAF) upgrade, the vacuum line for the MAP should not be used......

TFI = Thick Film Ignition system.

RE: how many vacuum lines are there and where are they?

the line they are talking about going to the exhaust is the EGR tube. the tube near the H pipe section takes exhaust gas and pumps it back into the intake.-used for pollution and fuel economy.(i got rid of mine lol)
there is a hole in the back of the head that needs to be pluged off by a bolt and the tube hole can be welded shut. a EGR plate will be needed to block the holes that go inside the throttle body.
