I got the same code after removing the solenoid assembly from the side of the abs unit. Because u have to move a lot of stuff out of the way to work on the ABS modulator the Evap canister may have been turned upside down and raw fuel may have clogged the line. I just cleared the code and hope it doesn't return. I used to get a gas gap code every month on my 2005 dodge Dakota! Evap is nothing to worry about.
