No problem
I compleatly agree with DAR the chain is not a problem and the aircraft can me flown untill you can get a maintenace company to have a look in the tank for you.
I would be prepared to lay a large bet that when the maintenance guys get to look in the tank they find at lease one of the plastic fuel level sticks in each tank!
After a guy admitted to droping one of these sticks in the tank of one of my aircraft a fleet check found five sticks and one fuel water sample tool across the three aircaft.
