heat in the area may have degraded the plug. Make sure the cap is the proper size and put a small zip-tie on it to keep it from sliding over the end of the vacume port.

A little dap of silicone adhesive on the plug/port when you put it on (let it cure before running the engine) worked for me for years now.

But I do like the idea of the small zip tie!!

Just a couple good ideas!
