Evap small leak
I have a 2001 ford expedition with 92k miles. Have a evap small leak I replaced the gas cap with Motorcraft. I replaced all hoses on gas tank I replaced the front silonid with a new Motorcraft hose going to intake. I replaced the filler neck hose. And I replaced the vent valve that goes on the charcoal canister. What could be the problem? I don't know what else to do

You prolly did this but I like to start with basic questions first:
Did you clear the DTC after all that work?
Did the DTC come right back?
And what DTCs are you seeing?
Have you smoke tested it yet?

Sometimes the large O-ring that seals the fuel pump cracks and leaks vapor. If you do decide to drop the tank and inspect it you might want to consider replacing the fuel pump at that time. Although the pump could last there's no guaranty and you'd hate to have to drop the tank again.
