One hose is reference the other is pressure, the hoses are different sizes, do you have the factory high-temp silicone hoses required? they are different sizes so you can't mix them up, vacuum hose will burn up in short order, the failure of this sensor is almost always caused by excessive exhaust back pressure, you may have a cat converter starting to plug up.

It is very likely that the vacuum hoses are the problem. The only people that have a manual with the diagram you need is a dodge dealer, contact the service dept at your local dealer and they will probably photo copy you a diagram from the service manual.

Most likely is a bad EVAP purge valve. But check below list.
This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled
by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank
into the engine to be burned, rather than be vented to atmosphere. A vacuum
switch is used to detect when flow exists. If the PCM commands purge and sees
that the switch is closed (indicating no detected purge flow) P0441 is set.

Likely, no symptoms will be discernible to
the driver, other than the illuminated Check Engine Light.
A code P0441 could mean one or more of the
following has happened:
