THE ACFT WAS LEVELED AND THE ENGINE STARTED WITH BOOST PUMP AND PUMPING THROTTLE. THE ENGINE WAS STARTED TWICE BUT WOULD NOT CONTINUE TO RUN EVEN AFTER FUEL WAS ADDED. FUEL VENTS AND LINES WERE OPEN. THE FUEL SYSTEM WAS FOUND NOT TO BE COMPATIBLE WITH THE FUEL SELECTOR PLACARDS, VALVE POSITIONS AND PLUMBING AS INSTALLED. ACFT RECORDS DID NOT INDICATE ANY CHANGES OR REROUTING OF THE FUEL SYSTEM. WITH ENGINES RUNNING AND BOTH ELECTRIC BOOST PUMPS OPERATING, UNCOVERING OF EITHER RIGHT OR LEFT WING TANK OUTLETS COULD INDUCE AIR INTO THE FUEL SYSTEM WHICH WOULD REQUIRE PURGING PRIOR TO NORMAL ENGINE OPERATION.
