Q: pump rattle - SHURFLO 4008-101-A65 Revolution

After a few months of very intermittent use it developed a rattling noise on low flow or before shutting down. Here is the noise, phone mike makes it more "rattling" than it is: https://youtu.be/S2Pte...

I tried to hold/move the pipes around. The rattle is coming from the pump. It is different from the noise that pipes make. It disappears for one day when I disconnect and reconnect the output with same pipes in the same position, and then re-appears again.
