WTB - Breather for 49-State 318/340/360 , 1970 - ???? .
It's the breather with 3 nipples ; one to the air cleaner base , one to the fuel bowl , and one to the fuel tank return line .

I've pitched ( not literally ) the vacuum-leak-infested EEC Canister, and now I want to add the 'correct' , non-EEC Canister-equipped
( " 49 State Emissions " ) breather to complete the job :happy7:.

Please be reasonable with the price , as I'm an underpaid Blue Collar worker . This part will be for my daily driver , not a restoration piece .

e-mail : 1972coronet@ca.rr.com

Thanks !
 
The breather I'm looking for was also used on 383's and 440's , regular as well as HP .

1970 - 1971 ; perhaps up through at least '75 or so on trucks and vans .
 
Er-ruh…what "EEC canister" is it that you've removed from your '70? The black plastic charcoal canister in the right front corner of the engine bay didn't appear til '72. The '70-'71 California and '71 50-state + Canada cars used the engine crankcase for fuel vapor storage. The '72+ system w/canister is much better than the '70-'71 system. See here for detail on both systems which may lead you to rethink how you proceed. If not, the 3-nipple breather is available as a reproduction item. Expect to pay Money for it, though! :shock:
 
Thanks for your reply , Dan .

I'm talking about my '72 Coronet . Its EEC "Charcoal" Canister has vacuum leaks galore , so I've removed it for the time being ; I'm going to fix its leaks eventually , but in the meantime , I'm looking to put a non-EEC breather on it .

I agree that the '72 & later EEC is better .
 
I just noticed the underscored "here" link to an earlier post , and decided to peruse it :happy1: !
Thanks for your detailled tutorial regarding the seemingly-esoteric ECS / EEC setup !
VERY cool !

Now , are you aware of the availability of the charcoal (replacement) and-or the filtre which mounts-underneath the canister ?
Also , it's good to know that the Purge Valve is still available :D .

Thanks again , Dan !
 
"EEC" = Ford's Electronic Engine Control system.
"ECS" = Chrysler's Evaporative (emission) Control System.

The breather cap you're after was used on V8s in '70 in California, in '71 in all 50 states and Canada, and…that's it. It is very difficult and costly to find. If this is just a quicky get-by deal until you replace the canister, you'd do better to simply drill holes in a regular breather and install threaded fittings for the two vapor hoses you want to route there.

And you probably should replace, not repair the canister. See last paragraph here for availability info on new canister. If you do decide to try to rebuild yours, the carbon is just activated charcoal granules you can probably get through an aquarium supply house, and the round filter pad is a commodity item from any parts store, Wix 42998 or NAPA 2998 amongst many other numbers. But you'll probably wind up cursing and swearing and buying the new canister anyhow.
 
Thanks again !

Thanks for clarifying the acronymns ; I'd always called it "EEC" for "Evapourative Emissions Controls" .

I'll check out the link you've provided . Thanks for the part numbers and the source for the charcoal :D .
 
As a side note :
I recently saw a 1971 Duster without an ECS Canister . It's a Los Angeles-built car , original California-spec build (L.A. built for the southwest primarily ) , original-issue blue/gold Ca plates ; built in Sept '70 .

225 / 904 combo . 2-outlet breather ; one line to the fuel tank , and one to the air cleaner base . No signs of ever having an ECS canister .

It appears that the application of the ECS in Ca-destined cars was almost arbitrary ! To wit :

- 1970 'Cuda 340 . Los Angeles build ; 727 trans ; standard hood . Sept '69 build . Original , non-preheat air cleaner ; no exhaust tips (N85 Noise Reduction Pkg) . Equipped with ECS .

- 1970 Swinger 340 . Original owner since day 1 . Untouched engine
( other than an MSD breakerless ignition conversion in '75 ) .
4 speed . Dec '69 build .
Same air cleaner as the previously mentioned '70 340 'Cuda ; however , it had factory-installed hood scoops with the cutouts opened .
No ECS canister !

I guess it depended upon :
- Carburetor ( single 4 Bbl , 3 Two Bbl or Two 4 Bbl AFB's )
- Air Induction ( "closed" hood vs. "Shaker" or "Air Grabber" )
- County in which the vehicle was sold new ( certain counties in Ca were exempt from Noise Reduction Packages as well as I/M Emissions Testing . This would explain how some Ca-spec cars had both "N95" as well as "N42" .

Again: What part do you have in mind when you say "ECS canister"? If you're talking about the plastic charcoal can in the right front corner of the engine bay, then no, a '71 wouldn't have it. It didn't come along til '72.

225 / 904 combo . 2-outlet breather ; one line to the fuel tank , and one to the air cleaner base.

That's correct. The carb bowl was ducted to a nipple on the fuel pump body, i.e., a clear path to the engine crankcase. The breather used on '70 California and all non-export '71 slant-6s had only one small-diameter nipple, which is where the fuel tank vent attached. Some V8s used a breather with two extra nipples, one for fuel tank vent and one for carb bowl vent.

In no case were these extra-nipple breathers used in conjunction with a charcoal can. When the charcoal can came in '72, the extra nipples on the crankcase breather went away.
 
Our '71 383 lo-po Newport has the 3 nipple breather while are '70 383 lo-po Newport doesn't if that means anything to you. Both are 49 state cars.
