Vacuum Lines

[68DartProject]

Kind of redeem myself here alittle.
And give this a go. Have a 72 318 Swinger. Made a choice to redo all the vacuum lines and before I could get home I had talked to my son about it and was at parts store to get new lines. Well to my surprise when I got home they were all off. He meant well and is learning. Now I have this problem that I dont know where any of them go from the coal canister to where ever. We had changed the intake to a eddy performer and a holley 600 single line electric choke. I know that from Holley they say the one in front on base plate goes to vac advance. the one towards the top on pass side is for pcv and the one in back goes to power brakes which i dont have so i plugged it. The can on fender goes somewhere in dash and to intake got that one. Just trying to figure the three from the coal can. I know one of these is the pcv. But which I dont know and have a mess here.
Thanks Michael

on the top of that can i am not sure but if you look close it should call out where each line goes /vent /pcv or carb does the car still have the hose routing sticker under the hood?

I would love to help you out but my 70 Dart does not have any of that stuff on it. I do have a 75 S/6 Duster with a mess of vac line going every where. Here are the two pics of it I have. Don't know that it will help you any but here it is just in case.

Good luck

I don't know anything about the coal canister but I will say this regarding the 600 holley vacuum secondary carbs:

the PCV goes to the large fitting on the baseplate that will be on the passenger side of the carb at the baseplate

The vacuum advance line for the distributor goes to the fitting on the main metering block. This will be near the top of the carb. If you hook it to the one on the baseplate, it will not be ported vacuum and the car will run crappy.

I will say typically there will be a fuel tank vent that goes to the charcoal canister, likely one to the PCV and I believe the 3rd one is for the bowl vent which you won't be able to hook up with a 600 holley.

From the '72 FSM, there are some color codes on top of the cannister?
White goes to the distributor
Red goes into a T in the line between the PVC and carb
Yellow goes to the fuel tank vent line
Black goes to the carb vent tube.

Here's a picture of mine just to make sure we're looking at the same stuff. I'm running a 318 with an LD4B and single-feed vacuum sec 600 Holley, so it should be close.


1. The small hose toward the top of the picture runs to the front of the carb baseplate (manifold vacuum)
2. The middle hose runs to the fuel tank vent line
3. The larger hose at bottom of pic used to go to the bowl vent... I'll eventually jam a cheap see-thru fuel filter in the free end to keep junk from finding a home in the canister

I dug through ALL my Mopar literature and the best I can find for you is this:

Honestly, to really remedy your issue, you need to get a Chiltons Service Manual that covers your 1972 Dodge Dart. Most vehicles have emissions routing stuff on a decal on the underside of the hood...for situations just like yours. Sounds like your boy made a young man mistake.....but I can understand because once I pulled all the spark plug wires off the cap and plugs and tossed them on the ground thinking #1 was marked on the cap, and the firing order was on the intake.....Doh!...no firing order on a Edelbrock Intake!!!.....and no #1 on a aftermarket replacement dist. cap.

Car sat in the driveway for a week till my uncle got back and made me memorize the firing order 1-8-4-3-6-5-7-2, Clockwise rotation, #1 is where the rotor lines up on TDC of #1's compression stroke....I'll never forget that lesson!

Hope that helps!!

Hey thanks guys all of that is of big help. After i cleared my head alittle and went out to look some more. I decided to take the whole can off and clean it up a bit the writing is worn but i could read it. I found on the top portion of this can where it says Dist vac, pcv and then fuel tank. I know where two of them go but have no clue to where i will hook up the fuel tank one. Im guessing this is fuel vapor or something. Can I just plug this off or do I need to put it into the intake somewhere? And the one on the fender is what I think may control my vent controls inside with the one going to intake as the main source of vacuum to it. And this one is right for sure.

Again Thanks
Michael

There should be a metal line that runs to your fuel tank that the hose connects to.

Good Job Jr. he's on the right track that boy of your's get out the trash can and put em in there,only lines that need to be hooked back up are the vacume advance,pcv valve,brake booster.the rest go into the trash can. the evaporative canister is a time bomb waiting to explode,the charcoal that is inside it will end up inside the carburetor and wreak all kinds of havoc.my buddie calls this procedure a "trash can job" and has performed this surgical procedure on my 88 chevy dually for me and now it always starts right up and the power and gas mileage has increased. HOORAY "trash can job" :cheers: :cheers: :cheers: and the metal line that goes back to the tank is for evaporitive emissions can be plugged also

Thanks Duster for running across that for me and posting it. I'm sure it will work out when I get to that part of vehicle.
