Fuel filter problems

I am having trouble disconnecting my fuel filter from the line running to the tank, has anyone else had this problem?

I was thinking of replacing the line but I can't get the clip undone (photo attached is where it connects)

I assume you cannot undo the pipe nut, a good set of tube spanners will help unless the nut has been rounded off badly.
If it is still ok perhaps get your mechanic to change the filter, a once off cost and easy for you to change in future.
