In the gas tank of the 2013 Toyota Highlander, you will locate the fuel filter attached to the fuel pump assembly. The manufacturer has designated this component as non-replaceable since it is designed to last the lifespan of the SUV. Replacing the fuel filter may often require replacing the fuel pump as well. As long as you use the correct unleaded gas with the appropriate octane rating, the fuel filter should function without issues. However, problems may arise from using low-quality gas. A new fuel filter typically costs between $15 and $25 and is readily available at most auto parts stores. Opting to have a mechanic replace it would involve significantly higher costs due to the labor-intensive process, with the total repair bill ranging from $300 to $500, inclusive of parts and labor.
In a 2013 Toyota Highlander, the fuel filter can be found inside the gas tank, specifically under the back seat.
Can you reach the gas tank to replace the filter from within the SUV?
