2008 petrol fusion,eml light coming on after fuelling

[Terry call]

Eml light illuminates after refuelling,any suggestions as to fault,,have to cancel light with reader

Hi I fixed mine by cleaning the filler cap, if the tank becomes a vacuum it will turn on the eml the ecu thinks that not enough fue is being delivered and increases the fuel which means it is running too rich and triggers a fault
