Departed runway 25R VFR normal take off roll, after gear retraction hydraulic lamp central warning panel on, performed memory items emergency procedure checklist applicable checks declared emergency configured aircraft landing runway 25R uneventful landing exited runway and came to a stop requested wheels chocked by crash fire rescue (crash fire rescue equipment). Crash fire rescue equipment confirmed chocked by company maintenance. During engine shutdown aircraft jumped chocks, propeller struck tug. Executed successful emergency evacuate/evacuation of passengers. Callback conversation with reporter revealed the following information: the reporter stated the cause of the loss of main hydraulic system and accumulator pressure and quantity was the failure of a nose gear flexible hydraulic line.
