When you see a distribution spool mounted in the center of the engine with a
1/8" line running to each cylinder head, that is constant flow fuel injection.
A positive displacement sliding vane pump fuel pump is gear driven from the
accessory section so the output is a function of RPM. There is additional
control offered by a valve controlled from the cabin (mixture) and I believe
another controlled by a diaphragm and spring to help account for altitude.

There are similar systems available for V8 engines, like Hilborne, Endrell
and others.
As far as I know any Continental injected engine is this system. Look at any
Bonanza.
