Abstract
A fuel supply system for an internal combustion engine is provided. The system includes a first pump adapted to generate a flow of fuel and a second pump in fluid connection with the first pump and adapted to increase the flow of fuel to a predetermined pressure. A fuel filter is disposed between the first pump and the second pump. A sensing line is adapted to provide an indication of the pressure of the flow of fuel between the filter and the second pump. A pressure regulator is adapted to receive the indication of the pressure of the flow of fuel and to control the flow of fuel delivered to the fuel filter based on the indication of the pressure.
