The pump runs continuously pumping much more fuel than being consumed maybe a liter every 5-10 seconds that goes out to the FPR and back to the left tank to siphon that to the right side which just spills out over back to the left side so it's exactly like a back yard water feature. In the tests for long term fuel pump testing they run the fuel in circles in/out of a 20-30 gal barrel for 4000-6000 hours until failure. Unless something is wrong you will not overheat a fuel pump pumping fuel.
Thinking though this again i would absolutely just disconnect the hose going to the engine, add a short piece of hose and let the pump do it's job.
I've run the tank dry before (both on accident and on purpose) and there was less than 4oz of fuel combined left the system is very good and emptying the tank.
The foot of the pump is toward the front and the siphon jet has a feet front and back so it'll drain better if you raise the back a bit.
Once pumped dry, add 2-3 gal fresh gas and run it dry again. What you don't want to do is run the pump after it's empty but it can handle that for "minutes" it won't self destruct in seconds.
