 When the spring fails the flap is still attached, but won't stay closed.  The PO of my van drilled a hole
 through the flap and the plastic underneath, then put a self tapping screw in to hold it down.  Its a bit of a
 pain, but if I leave the screw loose, I can remove it with my fingers when its time to connect water or
 power.  I think a magnet and steel place glued in the right places might work well too.
