fuel tank sensor hose connection is covered with plastic on 1999 Ford F-150

I removed the gas tank in my 1999 f150 to fix a leak. when I disconnected the hose for the sensor closest to the fuel pump (one of the two white plastic sensors) I noticed the end of the connection is covered with a plastic film. Is this supposed to be covered?
