Evaporation Canister Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone have some pictures of the correct hook-up of the hoses from the canister to the carb on a 72 350 engine. There are 3 hoses coming from the canister. 1 goes to the gas tank and I need to know how the other 2 hook-up.

Do you have a diverter valve cause that's where the purge valve on the canister usually goes.

I don't think so. 1 hose goes back to the tank. 1 hose goes to the front of the carb and the other hose is T'ed into the hose from the from the PCV valve to the carb. This didn't seem right to me, maybe it is.

Mine is the same as yours BigRand, and it's stock.

I'm pretty sure the pcv tee scavanges fumes from the block & maybe intake, while the carb hose scavanges fumes from the float bowl. Not positive, though.
