vaccum hoses

[Moxwell]

hello
I was trying to tighten up some of the air intake hoses as I was having a very low idle and I found one of the vaccum hoses from the distributor was off, the only available "plug" I could find was one that exited out of the passenger side firewall, it shares the opening with I believe to be the wiring for the antenna. Before I plug it in I want to make sure it is the correct one. Thanks, I ran a search but turned up nothing. Sorry forgot to mention it is the 3fe on a 92 LC.

Went out and did a quick check for ya:

I see two hoses that come out of the dizzy (or at least out of its rubber "jacket") along with the plug wires; one goes to the air cleaner, the other goes to a bon-bon size doohickie (technical term) attached to the side of the air cleaner housing. That line continues on past the coil, and then yes, into the firewall.

I don't think those have a vacuum in there, they're just vents for the distributor (breathers). Do you still have the rubber boot snapped on? I always thought that was cool about the 3FE, wish they would have kept it.

Yeah, I thought a little about this after I posted. It should be (slight, maybe) vacuum from the air intake, and the purpose is to breathe (dry) cabin air through the dizzy, right?

Still got my boot,

Correct. The dizzy is sealed for water fording, but is vented to the intake and to the cab through the firewall. Nice system, IMO...

Exactly the opposite of my old Volvo dizzy, which was OPEN on the bottom! Never did figure that one out - incredibly reliable vehicle as long as you didn't drive through any puddles!
