I got sidetracked with other non-pool projects since I hard to go parts for this but finally got back to this to give it a try. I picked up 4 clamps at HD (2 - 6" and 2 - 4") that worked out a little bigger than I needed but better than too short) and attached them together to make two large loops. I criss crossed these over the center of the pump strainer assembly and lid with some pieces of cut up weatherstripping to protect the plastic and help keep it from sliding off. I snugged the clamps down (not too hard) enough it give it a little pressure towards the center of the lid.
Great results.The lid no longer "burps" water when shutting off the motor and I don't have to go gorilla tight on the side screw downs. It looks a little "Macgiver" like (I guess that ages me) but preformance is more important to me so I'm happy with the results.
Great suggestion Poconos.
Thanks.
