charcoal canister - The 1947 - Present Chevrolet & GMC Truck Message Board Network

If you are keeping the rest of the equipment on the engine I'd run the canister. It acts as a filter for the vents on the fuel system on the engine and the tank and won't rob power or cause other issues. I've thought about putting one on my 48 and running a vent line to the tank just because I get tired of smelling gas fumes around the truck when it's parked and the heat from the sun builds pressure up in the tank that now vents through the vented cap.

I agree with 1project2many. Get your computer reprogremmed and ditch the rear o2 and cats. I would keep the canister though. Like mr48chev said, it will keep your truck fume free. On my 57 LCF, I used everything but the cats and rear o2 sensors from the 2003 chassis and running gear under it. Computer is happy and I can plug it into a reader and trouble shoot it.

I kept the canister on mine for the aforementioned reasons. It doesn't take up any space I'd use for anything else, and it was already on the s10 frame.

this wouldn't be an issue if mine was attached to the frame before, but it was attached to the sheetmetal on the Blazer. I can relocate it to the frame, but relocating those two steel lines running all the way from the engine to it was going to be more trouble than I wanted to go through (if I didn't need to). So I guess I will just have to relocate it to rear frame cross support.

If you seal the tank- gas cap, how do you seal the carb fuel bowl from venting in the 118* garage when the trruck sits for a week

He has fuel injection so he has no fuel bowl.
