Its very easy just get a fuel disconnect tool for a ford. the I forget if its the back one or second to rear one on the passenger side can be tricky because of the intake. but I have had them apart several times very easy just take your time and dont forget to grease the orings a little and make sure they are pushed down into the intake. and just snug up the screws for the fuel rail you dont have to make them super tight or they can strip.
