I need a way to vacuum hot oil without collapsing a vessel. We

using 55 gallon drums for oil that has cooled down, but, they will

when enough hot oil is vacuumed into them.

First thought is put a valve on the vacuum line, if you can't do
that
can you put an air bleed on the drum to control vacuum?

It would help to know how much oil is being picked up and it's
viscosity,
both hot and at ambient temp.

Can a paint pressure tank hold a vacuum?
