After hopefully degreasing my filter I'm having trouble getting the big lid gasket to reset. I've done it before intermittently but I really seem to be struggling now. The clamp bolts are not helping and I think I need to replace them as well. The threads seem to have gotten bunged up pretty good. The gasket wants to pop out when I repressurize the system after two attempts I gave in. In the meantime the water is going south on me. Any thoughts greatly appreciated.
