Hello All, Today, I set out to fix my loose power antenna bracket.. and upon removing the charcoal canister, there was a dry-rotted rubber cap on a fitting on the top of the canister labeled "CARB BOWL". The rubber cap was too rotted to keep... so my question is, should I find a replacement? Does it serve any purpose? What happens if I leave it off? Thanks in advance, -Hank #1619
