Tsunami MK2 T500 Manual Bilge Pump with Installation Kit - 500 GPH & 12V

This is a complete kit (includes a bilge pump) to install a manual bilge pump with a 3/4" I.D. hose outlet. The Tsunami Mk2 is the only manual bilge pump that eliminates airlocks. This is done by the Patented X-Air™ Impeller, which ejects trapped air in the pump and pipework.
