Nick , yes its cavitating , there is no filter on the outlet from the reservoir tank to the pump inlet so I am planning to replace the main filter thats the first thing the pump feeds to on the high pressure side , dont know if this will help as the cavitation is definitely happening on the inlet to the pump .
I know I'm a bit late with a reply here - only joined last week - but I think you'll find there's a strainer inside this reservoir, if we're talking about the same small one beside the pump. We had the same issue and narrowed it down to this reservoir, but which unfortunately seemed to be sealed with no way of opening it up.
Basically we had to cut open the end of the housing and found a choked up strainer inside, cleaned it all out and re-welded the end back on the housing, and bingo everything now worked fast and smooth.
