Lexus 23217-74021 Fuel Pump Filter

Relieve the fuel system pressure first, then disconnect the negative battery cable. Be cautious if your stereo is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery. If necessary for access, remove the air cleaner assembly and evaporative canister. If equipped with a union bolt at the top of the filler, use a backup wrench to hold the filter, loosen the bolt with another wrench and disconnect the fitting from the filter. Disconnect the fuel line fitting at the top and bottom of the fuel filter. On models equipped with a quick-connect fitting at the top of the filter, remove the fitting protector and disconnect the fitting from the filter. Loosen the filling at the bottom of the fuel filler with a flare nut wrench. Remove the bracket bolts from the bulkhead and remove the filler and bracket assembly. Note that the inlet and outlet pipes are clearly labeled on their respective ends of the filter and that the flanged end of the filter faces down. Make sure the new filler is fitted so that it's facing the proper direction as noted above. When correctly fitted, the filter should be fitted so that the outlet faces up and the inlet faces down. Using new sealing washers provided by the filter manufacturer, install the inlet and fillings and tighten them securely. If equipped with a quick-connect fitting, push the fuel line on the filter until it snaps in place and install the filling protector. The remainder of installation is the reverse of the removal procedure.
