Fuel filter is not servicable on that, you have to replace the pump to do it. You can thank the democraps for that. The fuel in a return style system heats the fuel n the tank after a while and makes it evaporate and destroy th atmosphere so on the return less systems that all new cars have put the filter in the tank as part of the pump, luckily they tend to be very large capacity filters so they hold a lot of crap before they cause problems and usually the pump dies before the filter gets full of crap anyhow.
