Cessna 340 crossfeed fuel and flying with my son

2 Days before this flight a transfer/aux circuit breaker popped on the right side while running the right engine on the aux tank.  I reset the circuit breaker and it tripped again.  This let me know that the aux/transfer pump was going bad.  On this flight to maintenance, the shop ask me to run the right aux tank dry so they wouldn't have a mess when they went inside the tank to replace the pump.  We only had a 1 hour flight.  After getting up to cruse I cross fed fuel from the right main to run the left engine, and ran the right engine off of the right aux.  We were able to burn the aux tank fuel level down enough so that fuel didn't leak out when the A&P went into the tank to replace the pump.  The considerations here are flying with a fuel imbalance, and monitoring the level in the main and aux on the right side while they both burn down at the same time.
