Abstract
A system and method for filtering fuel within a fuel tank is disclosed. A dual fuel filtration system may include a first fuel filter connected to a fuel tank opening of the fuel tank, the first fuel filter removing a first type of contaminant from fuel entering the fuel tank opening to obtain a fuel cleared to a first level. The dual fuel filtration system may also include a second fuel filter positioned below the first fuel filter and in fluid communication with a fuel outlet nozzle, the second fuel filter filtering a second type of contaminant from the fuel cleared to the first level to obtain a fuel cleared to a second level passing through the fuel outlet nozzle. The dual fuel filtration system may additionally include an interface portion connecting the first fuel filter and the second fuel filter.
