looks like EVAP hose

I believe that goes to a solenoid under the battery box for the Evaporative system.

Yes, it's a vacuum hose going to the solenoid which controls fuel vapors being pulled into the engine while running. So it could smell like gas if it's broken, and that solenoid switch should only open when the engine runs.

That hose is nylon inside typically only the outside deteriorates I hate that sticky black foam crap it gets all over everything.

If you have to replace it be careful the plastic fittings at the canister vent valve (under battery) are brittle.
You squeeze in the sides enough to make it fully round and then it should release

If the fuel vapor emissions hose is discontinued, some have replaced it with reinforced fuel injection hose with good results. As 410Fortune said above, the plastic fittings must be reused and care must be taken when removing.

Here's my solution from 2015 for my Sport Trac that's holding up well today. Good luck.

Anyone Else Have EVAP Hose Rot?

Touched the purge valve hose (4L5Z9G271BA) connected to the manifold and my hand turned solid black. It's also known as the Vapor Management Valve next to the power distribution box. Searched for an OEM replacement with no luck and used 3/8" Gates Barricade® Fuel Injection Hose (MPI) found at...

@rctx Have you read your DTC codes and are you getting a code #p 0455 Evaporative emission (EVAP) system -'large (gross) leak detected'?

 

[crunchie_frog]

If it is leaking in enough air, you will get lean codes.
