Hi,
Please delete repetitive posts.
Is it a new problem? If yes, check for process change and or equipment defect.

There must be a problem with the floating roof. Does the device only leak when filling the tank?

The roof is not properly floating. It is "sticking" against the wall causing pressure to build under the roof. So, it needs to be inspected and repaired.

Hi,
For process change, I was thinking new transfer pump with different head vs Flowrate.
Regarding equipment defect, do you have a preventive maintenance program in place for your storage tanks and associated equipment.

If pressure is being built up, breathers should release this pressure. Breathers are designed to do this as vapors and gas. Why would Oil comes out of breathers?
If the floating roof is stuck, rising liquid will eventually push all the vapors/gas out, but then, where will the liquid go as it continues to rise? Out the breathers.
