Bob,

Yes, no, maybe. Yes when it drops below the required minimum= =20 system operating pressure. No when the boost pump is limited in the=20 pressure it can produce to no more than the maximum fuel system operating=20 pressure. Maybe if the boost is too great. My single speed Duke'= s=20 boost pump does not overpressure the system.

BTW, one would think that systems equipped with a return line would ret= urn=20 fuel when the pressure/flow is greater than required, unless the return line= is=20 too small.
