Fuel filters are typically cylindrical with an inlet and an outlet port. Fuel hoses are connected to both the output and the input, forcing all fuel through the filter before it is delivered to your engine. As fuel passes through the filter, the filter element traps particles while allowing fuel to pass through. This is true whether you drive a diesel or gasoline vehicle. Fuel filters are commonly found under the hood in the engine bay or underneath the car near the fuel tank.
