<human>: What's the difference between an in-line fuel filter and a fuel filter that is mounted in the tank?
<bot>: The main difference between an in-line fuel filter and one that is mounted in the tank is that an in-line fuel filter is placed directly into the fuel line of your vehicle, while a fuel filter that is mounted in the tank is usually located inside the fuel tank itself. An in-line fuel filter is designed to remove debris from fuel as it passes through the filter, whereas a fuel filter that is mounted in the tank will typically only be used to clean up larger particles before they are allowed into the engine. Additionally, in-line filters tend to be more efficient at filtering out contaminants than those that are installed in tanks.
