Hammer Out My Fuel Filter

My fuel filter is disconnected from both ends and is just sitting there loose . It has a band on it that won't let the filter come off . I can't find a screw or bolt that would be keeping the band tight , but , it won't loosen up and give me my filter ! I have put a wrench on the tank side and hammered it toward the motor side ..slight success , but still it will not release the filter .
WHAT ! :runaround:

13mm socket, bolt goes through the plastic bracket into the frame. You need to look real close with your fingers ;)
