Narrative:

Student and instructor were inbound to the hagerstown VOR, when the engine sputtered and ran rough. We switched fuel tanks and the engine ran normally. As we were 3 mi from the hagerstown airport, the engine started acting up again. The student/owner called the tower and told the tower that he thought we were out of fuel and requested immediate clearance to land on runway 9. The tower cleared runway 9 and we landed with intermittent power, taxied off the runway, where the engine died altogether. Upon inspection of the fuel tanks, both were very low. The gauges read 1/4 on each. Lessons learned: when possible, always take off with full fuel tanks, especially if you aren't familiar with the aircraft you are flying! I will never trust the owners again!
