What is a 'bulk oil fill'

[Gardner Yeaw]

I have read about a bulk oil fill system but never got a good
description of what it is. I would assume is is a tank and a pump
arrangement. Is the pump manual of electric? How much oil does it
hold? Is there an aftermarket system available?

The reason I ask is that it is a pain to bring in the long funnel
and a container of oil plus rags or paper towels to clean up. It would
be nice to be able to top off the oil with the push of a button.
