Is my charcoal cannister really needed for anything?

[TxFiddler]

Hey guys, I was wondering about eliminating the charcoal cannister in my 80 C10 so that I could clean up a mess of vacuum lines.  Since there's no smog stuff or anything required, can the cannister be gone for good?  Any other suggestions on what else i could possible get rid of?

What are you going to do with your fuel tank vent?

[TxFiddler]

Vile, I guess that's pretty much the only purpose it's serving right now.  Are there any other alternatives or should i just leave well enough alone?  Any ideas are always appreciated. Thanks.

You can remove it but you'll want to vent the fuel tank still.

what i did way removed everything and cut down the vent tube for the tank near the sending unit. Its about 16 long rubber hose. The i put a differential vent on the end of that. And tucked it up so no water will splash on it. Been working good for me.

I removed the can on two vehicles dad's 84 c10 and my old mcss I just put on a piece of rubber hose and bent it downwards under the vehicle to vent.

You can also get vented gas caps. The one on dad's truck builds up pressure and always has even before the canister was removed, you go to tank the cap off and it'd hiss and flap and make noise out of the neck.

I have dual tanks, so I would need to vent both. Right?

Anyone got pics of how you vented your tanks! What kind of vent do you use?

[Swims350]

Like I said I just put a piece of fuel line on the metal hard line that went to the can and pushed it under the inner fender. That's my vent, or you can buy vented caps, and if you have dual tanks you'll need 2 vented caps.

I have a dual tank setup on one of my trucks. The vent is tee'd and runs along the frame in a metal fuel line. The Vent is capped near where the charcoal can was with a breather cap.

I got rid of all my emissions stuff on my 79 but left the canister with the fuel tank vent line hooked to it. So much room under the hood you don't really even see it.

Took out everything SMOG on 1985 Chevrolet Silverado and 1988 Chevrolet Monte Carlo SS and simply put rubber caps over the fuel tank vents on both vehicles.  After several years of daily driving both vehicles with routine oil changes and occassional spark plug changes, no ill affects whatsoever.

On the '88 SS, it lost SMOG, cruise control, air conditioner, heater, ECM and all related wiring, power steering, inner fenders, stock core support and a few other things.  Got rid of a lot of unnecessary junk that was cluttering up the engine bay.  I needed more room to change the spark plugs.
