A megapressure pump is a high pressure pump that serves as a component of an energizer. Apollo suggests replacing the turbolasers from three Vipers with megapressure pumps from a damaged energizer, allowing them to spray boraton into the launch bay that is on fire but cut off from the ship. The fireleader then has the idea to use one of the megapressure pumps to help boost the pressure in Galactica's internal hose system (TOS: "Fire in Space").
