It's typically mounted on a bracket just above the oil pan and in front of the fuel pump.
Here's a more specific description:
* Visual identification: The primary fuel filter is a cylindrical metal housing, usually with a plastic or metal cap on top. It's relatively large compared to other filters on the engine.
* Accessibility: It's usually accessible with a wrench or socket.
* Other nearby components: It's close to the fuel pump, the fuel lines, and the oil pan.
Please note: This is a general location. The exact position of the primary fuel filter may vary slightly depending on the specific year and model of your vehicle.
It's always best to consult your owner's manual or a repair manual specific to your vehicle for the precise location and instructions for replacing the filter.
