The hex on the screen is thin. Look at the end of your socket where it will fit over the nut and you will see a champer that needs to be removed (faced in a lathe) for it to fit up on the nut. I just cleaned two of these screens so I modified the overall length of the socket and turned the upper portion so that a pipe wrench would bite it better. It was TIGHT and difficult and will dump a lot of diesel on you for your troubles. The next one that I do will have the car up on its side and the fuel sending unit removed so that I can pump more of the fuel out.
It will run better after the screen is cleaned. My screen was cloged with a substance like mud with sand but the rest of the tank looked clean.
