i went through the back seat and used a pair of tin snips to get to the pump and the top cover. as for the torx screw pattern i don't recall that being an issue that i ran into.
once i got the fuel line and electrical switch off i took the ring off that holds the entire assembly together and then reached into the tank and removed the pump with a counter clockwise turn. the pump came apart at the tabs and the square filter just pops off. be careful with the float as not to bend it. the other round filter is on the bottom of the pump if it came out all together otherwise look in your fuel tank to find it. if you can try to get as much gas out of the tank as possible. i used some air intake cleaner and an air compressor to clean both of the filters. if only the alternator were this easy!
