My cap went bad and I replaced it with a new one (.04) and still had a overflow problem too. I did a lot of searching and read that the new caps are not as deep as the old ones. In a side by side comparison they looked the same to me. I tightened down the cap as much as I could by hand then when a tad further with channel locks. That fixed the issue. Hope this works for you.

Another way to check the system is with a pressure test.
