Narrative:

Maintenance had changed out a fuel control and performed engine checks leaving a 300 pound fuel imbal with a fuel load only 600 pounds less than capacity. While performing routine cockpit checks with a gpu. I began xflow to balance loads. I was then hailed by a dispatcher for a phone call from united states customs. I then turned off the aircraft inverters but left the aircraft battery switches on, forgetting about the transfer process. The right side soon reached capacity and began venting fuel -- about 20 gallons before being shut off. Fortunately the fuel remained in a small area and was vacuum recovered by airport operations. I will never again leave an aircraft unattended if electrical power is on or with an APU attached. I will recommend to the certificate holder to incorporate the above into the company manual and into the training program.

THE R SIDE SOON REACHED CAPACITY AND BEGAN VENTING FUEL -- ABOUT 20 GALLONS BEFORE BEING SHUT OFF. FORTUNATELY THE FUEL REMAINED IN A SMALL AREA AND WAS VACUUM RECOVERED BY ARPT OPS. I WILL NEVER AGAIN LEAVE AN ACFT UNATTENDED IF ELECTRICAL PWR IS ON OR WITH AN APU ATTACHED.
