I’m running a stock 340 with Holley 650 DP in a ‘73 charger. I’ve unhooked the charcoal canister and plugged the line leading back to the tank as the canister is not hooked up to the carb. Noticed the fuel tank is collapsing. I Am using a vented cap. Not sure if the charcoal canister removal did the deed or if the issue existed beforehand. Thanks for the assistance in advance.
