Where is the fuel filter located on the 2006 Buick Rendevous

The 2006 Buick Lucerne with a 4.6L engine does not have a traditional serviceable fuel filter that is easily accessible and replaceable like some older vehicles. Instead, the fuel filter is integrated into the fuel sender assembly, which is located inside the fuel tank. This design is common in many modern vehicles, where the fuel filter is not intended for routine maintenance and is expected to last the life of the vehicle.
If you suspect a fuel system issue or a clogged fuel filter, it's recommended to consult your vehicle's service manual or contact a Buick dealership for guidance. In some cases, if there are symptoms of fuel system problems, such as poor performance or hesitation, it may be necessary to perform a diagnostic scan using specialized tools to identify and address the issue.
If you are not experienced with working on fuel systems or if you are uncertain about the location and replacement procedure of the fuel filter in your Buick Lucerne, it's advisable to seek professional assistance. A qualified mechanic or Buick service technician can provide accurate information and perform any necessary repairs or diagnostics.

It should be on the fuel rail next to the fuel return line. some new cars have in tank fuel filter and pump and the regulator is in the fuel filter housing and there is no fuel return line.

You don't replace anything based on a code

You use trouble charts to diagnose the cause of
the codes & find the problem

could be alot of things but most normally it sounds as if the fuel pump may not be working correctly. whens the last time you had or changed the fuel filter could be dirty. have the fuel pressure checked. have you looked at your air filter? this is where i would start with the diagnosis

It is in the fuel tank, according to the documentation. It gets replaced with a fuel pump failure.
