Yep, I understand this part of the Accusump or "accumulator" setup.
Pre-oiling is a def. win.

I understand... I'm trying to find out if folks ever see "oil cavatation"
or tht kind of thing. On some of my earlier cars (VW Beetles in
particular), I was was easily able to "slosh" all the oil to one side or
'tuther in hard cornering resulting in momentaryloss of oil pressure.
That VDO electric oil pressure gauge was sure fine at pointing that out!
Disconcerting, for sure, but I never spun a bearing or anything with
those cars. Of course I did rebuild the engines with greater regularity
than my Triumphs... but what the heck, I was young-ish.
