It's part of the fuel sending unit
The fuel filter on a 2006 Nissan Frontier is located inside the fuel tank. It is part of the fuel sending unit, which is situated inside the fuel tank, and it requires dropping the tank to access it. This is a complex process that may be best left to a professional technician.
The fuel sending unit is a component that sends a constant signal indicating the amount of fuel remaining in the tank. It achieves this through a mechanical arm that extends to the top of the fuel, floating on its surface. As the fuel level decreases, the arm moves down, resulting in a decrease in signal strength from the sending unit. This information is then transmitted to the fuel level gauge, providing the driver with valuable data.
When the fuel level is low, the sending unit triggers the dashboard light, alerting the driver to refuel. If the fuel sending unit fails, the fuel gauge will cease to function, and in some cases, the check engine light may illuminate.
Replacing the fuel sending unit can be challenging, and the level of difficulty varies depending on the specific vehicle. In some cases, the fuel tank must be removed to access the unit, which is a cumbersome and heavy task that requires an assistant for safety. Additionally, the sending unit and fuel pump are often replaced together, and they are unbolted from the fuel tank and disconnected from fuel and electrical connectors.
It is important to note that fuel contaminants can significantly impact the health of the engine and fuel system. Therefore, it is essential to use the appropriate grade of fuel as specified in the owner's manual.

However, it is recommended that you check the fuel filter regularly and have it cleaned or changed as necessary. This is because a clogged fuel filter can cause problems with starting, stalling, excessive vibration while driving, and rough slow-speed cruising.
If you do need to change the fuel filter, it is possible to do so yourself, but it can be a complicated process. The average cost to change a vehicle's fuel filter is between $90 and $207, including parts and labor.
