The second picture shows the pressure and return lines for fuel going to and coming from the engine. They might leak fuel if it's a bad connection.

The nipple/pipe not connected to anything is a crankcase vent line that gets tied to the charcoal canister by a hose that is connected to a hard line clamped to the firewall. Sorry, I've never seen fuel dripping from the hardline coming from the charcoal canister...ever. Then again I've never looked .

There's another hardline that goes to the charcoal canister that originates from the fuel tank three way checkvalve and THAT line might have some fuel in it but in tiny amounts. see jpg attached.
