Abstract
A filtration system is provided. The system provides a first filtration loop that provides one or more passes through a first filter using a first pump and a second filtration loop that provides one or more passes through a second filter using a second pump. The combination of a first pump and a second pump, each with a filter and each running independently of engine speed, provides an effective means of cleaning fuel.
