do i need these?

the one closer to the fire wall has the line come from the top of the gas tank and the one in front of the shock tower has a line that came from the intake manifold and then went into the firewall. im guessing that one is for the ac. but im not useing the ac anymore on the car. im in the process of sanding down my engine bay to paint it and this is why im asking if i need to even worry about putting them back on. thanks

 

NOPE...:Handshake

 

If your still using your Heat, you'll need that vacuum canister (left arrow)

 

I use my heat and defrost, and took out the vacuum canister...

Should I not have?

 

You need the vacuum to move the flaps around, without it, your stuck in defrost.

 

It's only illegal IF you get caught. Have you ever seen someone prosecuted for this ? I'll bet there hasn't been one single case since that BS was mandated. F--kin ****'s Fugly and needs to be removed. A simple hose run from the tank to the aircleaner serves the same purpose. Which is what I did with the vent on my 89 Ranger after converting it to a carbed V8.

 

Only if the engine isn't running. When the engine starts up, I hear the flaps switch to heat.

Mine runs off of intake manifold vacuum, believe it or not. Which means it probably flips to defrost when I gun it then back to heat when I cruise. I have the vacuum line off the manifold T-d off to the dash and to the transmission vacuum modulator. Only other vacuum lines in my entire engine bay are PCV and distributor vacuum advance.

 

ok so the fuel canister i legally need but could take it out if i really needed too...(might as well just keep it dont need the area there for anything) ..... and the vacuum canister like scooper said you just basically too the line that ran into the can and the one that came out and connected it so it bypassed the can right? like what does the can do? mine isnt air tight at all to make any kind of vacuum

 

It is a charcoal cannister, it holds fuel vapors when the car is off and sends the vapors to the carb when the car is running.

 

Chunk it. Chunk it all.

 

...and how long is the...carbon...good for? does it ever have to be replaced? how do you know if it's still good? is there some way to test it?


...i tossed mine with the 6 cyl...

The only issue getting rid of the cannister is what happens to the fuel vapors?? Now you have a vapor line coming into the engine compartment filling under the hood with gas fumes especially on fill up. Not really a good idea. Paint the cannister black and connect it like it should be. Thats my 2 cents.
Either that or change the location of the vapor line.

 

you can move the charcoal canister to back by the tank. you can get a modern one off a new car that are located back there already. they are slim and would be easy to mount back there.
