You were sucking air in the pump. That is a disaster waiting to happen. SVO is correct the fuel cools the pump. Not only internally but also externally. Never do these two things with an intank pump.
1 never run it below 1/4
2 never fill the tank with the car not RUNNING

Ummmm, Gas stations have signs that tell you to turn off your car while filling. I'm not sure what goes on down where you live but they wouldn't like it if you kept your car running while your pumping it up.:headscratch::headscratch::headscratch:

there was no air being sucked by the pump. the gasoline cools the pump as well as insulates the sound. you heard the sound of the pump. not a big deal. just dont run it for a long time with that little amount of gas

When the fuel gets low the pump does make more noize because the fuel around the pump insulates the noize. But it also can suck in air when the gas sloshes around and that causes noize. Modern pump systems are incased in a plastic cavity on new cars to stop airation from slosh. As far as keeping the car running. 80% of the pumps we replace have recently been filled up. Pumps fail most of the time when they are low on fuel and being refuled. If the car is running the pump is being cooled. If its off the pump is real hot and the cool gas coming in on refule shocks the pump internals. I an totally awaire of the rules on the pump that say engine off and no sparks.

My 88 I had had a noisy pump. It would always groan but be really loud once it got below half a tank. I had a new pump installed and it was totally silent all the time. Once the pumps get some age and wear on them, they will start to get noisy.

The rule of thumb on an in tank pump is replace it at 75,000-80,000 miles if it has never been changed
