Narrative:

Prior to performing maintenance myself and my partner discovered that a screwdriver and flashlight were missing from his tool box. After consulting with my partner we realized that we forgot to reinstall the cover panel for the tail tank's r-hand fuel boost pump the previous day. My partner and myself had a miscom after testing the pump; I thought he had installed the cover; and he thought I had; but in fact the items were left on the aircraft. After discovering this problem we immediately notified our manager; who in turn notified maintenance control to call the station down line to correct the situation.
