No dog in the hunt, but,
The Dawn Patrol (imitation WW1 aircraft flying group near KC) made famous the use of windshield washer pumps as smoke oil injection pumps.

I'd suspect that both the little single shot manual pumps or the windshield washer pumps would be rather slow transfer devices compared to just pouring in a pint of oil for 16 gallons (or a half-pint for 8, etc).

Having to string a cord out for power would be the only real drag, IMO.
As far as pumps go for adding 2-stroke oil to the fuel inlet ....... couldn’t you just use a windshield washer pump?
Shoot, you could probably get away with using the reservoir as well.
