What's the difference between an in-line fuel filter and a fuel filter that is mounted in the tank?

The main difference is that an in-line filter is placed directly on the fuel line, while a tank-mounted filter is usually located inside the tank. An in-line filter is typically smaller than a tank-mounted filter, as it does not need to handle the entire volume of fuel that passes through it. In addition, an in-line filter is designed to be replaced more frequently than a tank-mounted one, since it can become clogged much more quickly due to its proximity to the fuel pump.
