Im trying to eliminate the Charcoal Canister on my 86 K5 Blazer, but im confused on how to do this. I have three lines coming from my sending unit. A gas line, a vent line, and a line that goes to the EGR valve. How do I go about eliminating the Charcoal canister, and what do I do with the un-used lines on the sending unit. Just plug them up..? Also, I have a Holley square bore carb, 600 electric choke.

Thanks.
 
Sending unit (fuel tank, right?) lines should be fuel, fuel return, and EVAP (breather) line. Not sure why EGR would have anything to do with the canister unless it was how GM shared vacuum for the switches or something.

To eliminate the canister you need to put a breather on that line from the tank.

Personally I'd not encourage it BTDT, fuel vapors and all, but up to you.
 
I don't think there's any point removing it. I don't think there's any benefit. It just stores vapors and releases them into the carb. What are you trying to do?
 
All I can tell you is that my charcoal canister wasn't working and my truck always reeked of gasoline. It was unbearable. I'd never do that on purpose....

I used to have a '84 Dodge Caravan like that. It would pressure up the fuel tank more than any vehicle I've ever seen. I did some reading and what I found is if you can smell gas then the charcoal is saturated and needs to go. I never fixed it, though. The trans went out and I got rid of it. I read that "topping off" the tank overfills it and gets gas in the return line and can quickly saturate the charcoal. I'm thinking on a 25 year old truck it's probably just shot. If it ever starts happening with my Suburban I will replace it. Gasoline constantly emits vapors and the cannister has a place, as far as I know it's not restrictive.
 
I'm putting my charcoal canister back on and I'm running a fuel cell. The breather with fumes coming out scares me. Especially when people are smoking around my truck
