Claim:
1. A fuel management system comprising: a first fuel tank; a second fuel tank; an intelligent crossfeed valve positioned between the first fuel tank and the second fuel tank and configured to be open by a first predetermined amount to allow fuel to flow between the first fuel tank and the second fuel tank at a first rate and to be open by a third predetermined amount to allow fuel to flow between the first fuel tank and the second fuel tank at a third rate that is greater than the first rate; a sensor configured to detect an amount to which the intelligent crossfeed valve is open; and an engine controller connected to the sensor and configured to cause the intelligent crossfeed valve to close in response to the intelligent crossfeed valve being open by the third predetermined amount to reduce the likelihood of providing fuel to a leaking fuel tank.
