I'm hoping that as it happened nearly four years ago, he got the filter off.

My pickup did this, the plastic ball and socket joint wears and it'll pop off under any pressure.

If it keeps popping off, I had to drill though the socket and tap a thread in the ball and stick a bolt in it. but you may be all right and its just popped off.

Yes I know 4 years old but this is a tip in case your stuck.
These sockets can be temp repaired by linning the socket with a quality street sweet wrapper, now here me out on this you need one that has the shiney metalic inside coating honest their fe cin indistructable and will do until you can be a rsed doing the above proper fix or getting a new one.
