Where is the fuel filter located on a 1994 Lexus LS400?

the fuel filter is located behind the back seat...there is a 9" access port in the center of the fuel tank behind the back seat. located in the center of the open port you will see a fuel hose with some hose clamps....the 3 semicircular bolts that line the bottom of the portal anchor the bracket that holds the fuel filter mounted deeper in the fuel tank.
