How far away is the Outside receptacle? If its not too far just use 12ga (2) conductor with ground direct burial cable to a weather proof receptacle box mounted on a post near your pump. On the other end of the cable install a male (3) prong plug. Just bury the cable at least 16 inches deep.
By the FL Electrical code its an extension cord and not a new circuit.
If this is something you want to do I'll walk you thru it..with some pic's..
