Look what I found about the P-47 while searching for one of Bodhis endless questions:

Lubricating oil was carried in amagnesium tank of 28.6 U.S. gallons capacity, strapped to supports on the engine mount. A pendulum was in-corporated in the tank to insure ade-quate lubrication for inverted flightsof limited duration

powered by a Wright Cyclone R-1820-GI 1,000 hp engine and a three-blade Hamilton Standard propeller the aircraft was equipped for inverted flying for periods of up to half an hour.

A second scavenger pump and five drain lines enabled the plane to sustain inverted flight for up to 30 minutes.

sorry, but the F3F flight manual I have mentions nothing of being equipped for inverted flight for up to 30 mins.

Which to believe, someone's website, or the real thing...

Never Know by Jack Johnson

I hear this old story before
If people keep appealing for the metaphors
Don't leave much up to the imagination,
So I, wanna give this imagery back
No it just aint so easy like that
So, I turn the page and read the story again
And again and again
It just seems the same, with a diff. name
We're breaking every building
And we're growing
Always guessing

Never knowing
Shocking but we're nothing
We're just moments
We're Clever but we're clueless
We're just human
Amusing but confusing
Were trying but where is this all leading
Never Know

It all happened so much faster
Than you could say disaster
Wanna take a time lapse
And look at it backwards
From the last one
And maybe thats just the answer
That we're after
But after all
We're just a bubble in a boiling pot
Just one breath in a chain of thought
The moments just combusting
Feel certain but we'll never never know
Just seems the same

Give it a diff. name
We're beggin and we're needing
And we're trying and we're breathing

Never knowing
Shocking but we're nothing
We're just moments
We're Clever but we're clueless
We're just human
Amusing but confusing
Helping, we're builign
And we're growing
Never Know

Knock knock on the door to door
Tell ya that the metaphor is better than yours
And you can either sink or swim
Things are looking pretty grim
If you dont believe in what this one feeding
Its got no feeling
So I read it again
And again and again
Just seems the same
Too many different names
Our hearts are strong our hands are weak
We'll always be competing never knowing

Never knowing
Shocking but we're nothing
We're just moments
We're Clever but we're clueless
We're just human
Amusing but confusing
But the truth is
All we got is questions
We'll Never Know
Never Know
Never Know

Other than the carburetor issue I suspect the question is how a dry sump works when the engine is inverted. If the scavenging pump is drawing from the bottom of the block and all the oil is instead at the base of the piston... That's what the links here seem to suggest.

The place to find all this stuff is Graham White's books on Allied Engines of WWII.

The F3F had a scavanger pump to allow for sustained inverted flight, but the F6F, F4U, and P47 did not.
