where is the evap purge solenoid valve 2009 f150

What is your question?

After filling the gas tank the amount is limited to much less than the tank holds. 17 gallons on a 26 gallon tank. Now after filling gas, its hard to start the engine. Also its stalling while driving, hard to idle at the light.
