Took it in to the large ford dealer here and they wouldn't look at it because it's a "RV" I made the apt for a E-450. 2018 Thor Axis.

What Does P0496 Mean?
The Evaporative Emission Control (EVAP) System seals the fuel system of the vehicle in order to prevent fuel vapors from the fuel tank and fuel system from escaping into the atmosphere. This is important because fuel vapors contain a variety of hydrocarbons. Hydrocarbons form smog when they react with air and sunlight. Gasoline evaporates very quickly, so if the fuel system is open to the atmosphere a vehicle can pollute 24 hours per day without even being turned on. These uncontrolled evaporative emissions account for as much as 20% of the pollution produced by a vehicle! When trouble code P0496 is set, it means that there is an issue with the purge flow in the EVAP system.
P0496 Symptoms
There may not be any noticeable driving issues with your vehicle but your engine could be running rich which could cause internal damage to your engine. There may also be a rough start when cranking the ignition.
P0496 Causes
Faulty purge or vent solenoid/valve
Faulty EVAP/fuel pressure sensor
Blocked vapor canister
Leaking evap system hose
Blocked vapor canister
Poor electrical connections
