This Instructable will show you how to replace the in tank fuel filter on 2006 - 2010 Toyota Camry 4 cylinder cars. I am pretty sure that this will cover later model Camrys as well but you would have to check with your Toyota dealer to see if the fuel filter for your vehicle is the same as what I describe here for this model range.
When you purchase a Toyota fuel filter (genuine or aftermarket), this is what is supplied, the top cover connected by the fuel outlet hose to the filter. After you have removed the fuel sender / pump / filter (FSPF) assembly from the fuel tank, you will be removing the fuel gauge sender assembly and fuel pump from FSPF and refitting them to the new filter/ top cover assembly.
