Vapor canister filter..?

[Peer81]

Hello,

I'm in the middle of a body off resto and changing all bearings, bushings and filters i can find.
I've orderd a canister filter for my 81 but here comes the problem.
The workshop manual says something about the canister but not how to open it or to change the filter. On the bottomside i can see two openings to close/lock the canister but not to open it. (One way lock.)

Could anybody explain how i can change this filter. Its a sort of glasswol (thin hairs) about 1/4 inch thick and 4 to 5 inches in diameter.

Groeten Peter.

Just saw this

I just came across this and noticed no replies. I'm not absolutely sure on the '81's, but on the '70's cars the vapor canister filter was accessed by prying off the bottom cover on the canister. I would loosen the bracket, slide out the canister, flip it over, and pry off the botton cover with a screwdriver, pinch the filter center, pull out, and gently smooth the new filter in (a mini screwdriver helps lay it down nicely). Then reassemble. Piece of cake.

On the 77 you pull the old filter out and slide the new one back in. Nothing to be undone.

Bob,

I have never really paid attention to the canister in my 73. All of the emmisions were taken off before I bought it. After running mine on the street I will get a gas smell in the garage at times after it sits for a while. No leaks anywhere but I did look at the canister tonight. Looks like one hose is running to the rear and the other one was just cut off. Would the one that is cut create the raw gas smell that I get at times?????

 

[Bob Chadwick]

The cut line is the one that draws the vapors into the carb to burn. If it isn't attached, the fuel tank is venting to the air.

Thanks....not sure why it was cut but it may be time to look at the filter and hook it up

This is part of the emissions system, supposed to eliminate gas fumes in the atmosphere or some bull!! If your car doesn't have to comply with the smog stuff it could be disconnected, as Bob said it just purges the tank of fumes and puts them back into the vacuum port on the carb.

You must use a vented gas cap if you plug the line.

Thanks

Thanks Bill......that was my next question....I will get a vented cap and cap the line. Hopefully that will stop the gas smell I get in my garage for a couple of hours after shutting it down

Bob where do you buy the filters? Thanks Chuck

 

[JOE BYRNE]

Ever see this car

Chuck,

I sent you an e-mail

 

[Bob Chadwick]

I think I bought it at Doc Rebuild.

 

[Peer81]

Thanks for the replies everyone!

@Bob, did your filter have the same cross section as the canister or smaller?
I can't find a place to slide the filter in and out, and the filter is much smaller than the cross section of the canister (indeed doc rebuild).

Greetings Peter.

Peter,

It's been a couple of years but as I recall, the filter was the same diamter as the canister and sat at the bottom. There was a thin plastic bar that ran across it and held it in in the middle. I pulled the old filter out and slid the new one in behind the bar and around the edges of the canister.

My filter was a circular shapped piece of cloth. There was no stiffness or frame to it and so it just folded up into place.
