Some sources suggest replacing the fuel filter before running an injector cleaner through the system, as this can help to prevent any dissolved gunk from passing through the injectors. Others recommend replacing the filter afterwards, as it can trap any debris that gets loosened from the tank during the cleaning process.
It is important to note that newer vehicles may have a filter located inside the gas tank, which is only replaced when the fuel pump assembly is changed. Additionally, today's vehicles may not require fuel filter replacements as frequently as older models due to improvements in fuel quality and vehicle technology.
