Narrative:

During a night cross country flight my student and I diverted after noticing that the fuel gauge was dropping faster than normal. We had departed with over 2 hours of fuel for an hour flight. We diverted 5 minutes after takeoff when we felt that things just weren't going well. We topped off the tanks with 21.5 gallons. That means we landed with 2.5 usable gallons of fuel. We took off with 2 hours of fuel onboard but landed with 20 minutes after only a 15 minute flight. The source of the problem was a loose fuel line going to the fuel pump. The airplane was just out of its 100 hour inspection.
