Motorcraft 2100 Vacuum Line Routing
 
I finally got tired of fighting my Carter BBD and decided to try the MC2100 conversion. Below is the way I plan to route the vacuum lines. Please let me know if something is not correct or I totally missed a line. The color code refers to the color of vacuum cap. I tried to make this as easy to follow as possible in case someone stumbles across this thread with the same questions.

*EDIT I ended up adapting my factory air cleaner so I have to make some changes for my setup. a * indicates these.

Red (Pic 1)- crank case breather. I plan to use a Fram BA6592. *Capped with factory air cleaner.

Black (Pic 1)- PCV valve

Blue (Pic 2)- distributor if you plan to run ported vacuum. My would over heat at idle on ported so I ended up connecting to manifold vacuum on the distributor vacuum advance. *Connected to hose on factor air cleaner that opens the vent for air flow.

Red with hot pink line (Pic 2)- to charcoal canister port closest to the firewall.

Black with pink dot (Pic 2, look for pink dot at the base of carb)- CTO port #1 shown in Pic 4.

Blue (Pic 3)- CTO ports #2 & 3(Pic 4) should be connected with a tee and connected to this port.

Black (Pic 3)- Brake booster

Red (Pic 3)- Connects to the Vac switch on the firewall.

Port #4 (Pic 4)- connects to charcoal canister closest to front bumper of Jeep.

I've got my booster coming off of black in pic 3. Not sure if it's a good way to do it. The hose was the right size so I went with it.

Sent from my phone because I'm doing something "more important"

Thanks for the response. That's where my brake booster is connected also and was connected there when I bought the Jeep. I had to pull the intake off to replace a cracked exhaust manifold.

Does this look right to everyone else? Does anyone know what to do with the Red in Pic 3.

That looks correct (off the top of my head). The black port in pic 3 I used for PCV since I have an older MC2100 without the PCV port on the rear of the carb that you have. Since its not needed, capping it should be fine.

Your dist needs to be hooked to manifold vacuum - Your blue cap in pic 2 is demand vacuum - leave it capped for your conversion
Along with this you need to make sure your dist has the correct mechanical advance setup in it
You are doing the bypass or is it already done?

Cashcrazy 07-12-2013 03:17 PM

Bypass is complete.

It would be great for a finish pic. Got one?

Cashcrazy 08-11-2013 07:41 PM

Which area are you needing to see?

rocketboy 08-11-2013 09:43 PM

I'm having trouble sourcing the breather BA6592. Could you share where you've found one?

Cashcrazy 08-11-2013 09:50 PM

Autozone carries them. They had a store brand and not the FRAM. They should be able to cross reference it for you. They are all hanging in the front and I just found what I needed without having to wait on someone to help me. BUT I ended up not going that route. I am adapting the factory air cleaner to the MC2100.

rocketboy 08-11-2013 10:29 PM

Ok thanks. I had no luck at autozone, o'reillys, and advance auto even cross referencing but I'll try again.

Sorry for the thread hijack...

Cashcrazy 08-11-2013 10:55 PM

I found them hanging where the fuel filters and PCV valves are, try that area.

Cashcrazy 08-17-2013 11:21 AM

I had the parts clerk at Advance Auto look up the breather filter while I was in the store hoping I could get a little more info for you. They cross referenced it to a Purolator B23165. Try to find a Fram BA6592 or the Purolator B23165, either should work. They are also availble on eby for a few dollars more if no one has it local. Good luck.
