What You'll Learn
The fuel filter is in the gas tank
The fuel filter in a 1999 Lexus RX300 is located inside the fuel tank. This is part of the fuel pump assembly and should not need to be replaced unless the fuel has been contaminated.
Lexus RX300 owners have reported that the fuel filter can be accessed by removing the rear seat, where there is an access hole. However, this is a difficult process, and some recommend using a fuel system cleaner instead of replacing the filter.
In-tank fuel filters remain clean due to the sloshing of fuel in the tank. The movement of the fuel causes junk to form a sediment at the bottom of the tank, which means the filter does not need to be replaced often.
If you do need to replace the fuel filter, you will need to jack the car off the ground. The fuel filter is located under the vehicle on the driver's side, in front of the rear wheel well. One end of the filter can be disconnected with a wrench, and the other end has a plastic clip. Be sure to have rags on hand, as fuel will leak from the tank when the filter is removed.

It's rarely replaced unless fuel is contaminated
The fuel filter on a 1999 Lexus RX300 is located inside the gas tank, as part of the fuel pump assembly. It is rarely replaced unless the fuel is contaminated.
Fuel filters are designed to remove contaminants from the gas before they can reach the fuel injection system and engine. Over time, the fuel filter will collect and hold onto the particles it removes from the gas, which eventually clog the filter and impact its effectiveness.
A clogged fuel filter can cause issues with the engine, such as erratic fuel flow, longer than usual cranking before the engine starts, frequent stalling, poor fuel mileage, rough idling, and a strong gas odor. However, unless the filter is totally blocked, a bad fuel filter will rarely prevent the engine from starting.
In the case of the 1999 Lexus RX300, the fuel filter is not typically replaced unless there is a problem with contaminated fuel. This is because the in-tank filters remain relatively clean due to the sloshing of fuel in the tank, which causes junk to form sediment at the bottom.
To replace the fuel filter on a 1999 Lexus RX300, you would need to remove the rear seat to access the fuel pump assembly through an access hole. However, this process can be challenging, and it may be preferable to use a fuel system cleaner to improve the performance of the vehicle.

It can be accessed by removing the rear seat
The fuel filter on a 1999 Lexus RX300 is located in the fuel tank, which is part of the fuel pump assembly. It is not typically necessary to replace the fuel filter unless the fuel has been contaminated. However, if you do need to access the fuel filter, it can be reached by removing the rear seat on the driver's side. This will expose an access hole that leads to the fuel filter.
Lexus has thoughtfully designed the RX300 to allow for easy access to the fuel filter from inside the vehicle. This means you won't have to deal with the hassle of dropping the tank or accessing it from underneath the car. It's important to note that fuel filters in the tank tend to stay clean due to the sloshing of fuel, which causes junk to form sediment at the bottom of the tank.
If you're considering replacing the fuel filter yourself, it's important to exercise caution as there is retained pressure in the fuel line. Make sure to take the necessary precautions to prevent fuel from splashing inside the vehicle compartment. Additionally, keep in mind that fuel filters are inexpensive and easy to find if you need to replace yours.
While it's not a common maintenance item, knowing how to access and replace the fuel filter in your 1999 Lexus RX300 can come in handy in the rare case that it needs to be done. Remember to always put your safety first when working on your vehicle.
