Narrative:

Owner refueled airplane while I did flight planning and checked WX for flight to ZZZ. All 4 tanks were topped by FBO. I did not physically check these tanks. Subsequently. The engine lost power and a landing had to be made on a road. This even though the book (poh) indicated plenty of fuel to destination and legal reserves with fuel beyond. It is unclr whether fuel caps leaked in-flight, fuel did not xfer completely from tip tanks to main tanks, fuel did not flow from main tanks to engine, fuel leaked from engine fuel pump or elsewhere. To prevent recurrence: know your airplane and check fuel visually.

Narrative: OWNER REFUELED AIRPLANE WHILE I DID FLT PLANNING AND CHKED WX FOR FLT TO ZZZ. ALL 4 TANKS WERE TOPPED BY FBO. I DID NOT PHYSICALLY CHK THESE TANKS. SUBSEQUENTLY. THE ENG LOST PWR AND A LNDG HAD TO BE MADE ON A ROAD. THIS EVEN THOUGH THE BOOK (POH) INDICATED PLENTY OF FUEL TO DEST AND LEGAL RESERVES WITH FUEL BEYOND. IT IS UNCLR WHETHER FUEL CAPS LEAKED INFLT, FUEL DID NOT XFER COMPLETELY FROM TIP TANKS TO MAIN TANKS, FUEL DID NOT FLOW FROM MAIN TANKS TO ENG, FUEL LEAKED FROM ENG FUEL PUMP OR ELSEWHERE.
