Yep! I had the same issue with my 1262. I found some bulk rubber gasket material that comes in a 12" wide roll at ********'s. They will cut to length for you off the roll. It's in the plumbing dept.
I also saw one guy on another forum he glued two pieces of old clear hose to the bottom of his pump looked like a good idea. I just put a piece of a sponge filter under mine and then use if for my qt tank when I quarantine a fish for the bacteria.
