This is the main reason fuel pumps fail, no fuel to cool them.
Always keep it over a quarter tank........

This is a myth, I think it may have been true on older cars but I have
always used all of the fuel before refilling the tank and have never had to
replace a fuel pump. The fuel pump isn't cooled by being submerged in
gasoline, it is the gasoling flowing through the fuel pump that cools it.
Just my opinion. Anyone reading this can do what they want.

I would "think" an Object completely surrounded by a cool liquid would have
a tendency to cool itself ? Ummmmmm

What I mean is that it doesn't need to be submerged to stay cool. As long
as it is pumping fuel it will stay cool.

I've drive on "E" with the idiot light on quite frequently and been doing
iot for 30+ years. Not a single fuel related issue so far. My current
vehicle has 3-4 gallons left in it when the light comes on. I often drive
2-3 days that way. I vote that it's a myth as well.

change fuel filter regular makes the pump last longer.

It's both, plus fuel slosh going around corners starves the pump and it runs
dry for a second.
Even in it's baffled tank setup it will suck air as it's moving a lot of
fuel in a recirc. system.
Keep gas in the tank

I don't know why people tell me to do this, I don't plan on doing it
because I've always let my tank run dry before refueling and never had to
replace a fuel pump. I've owned cars as old as 1985s and as new as 2004s,
never had a problem on any of them with the fuel pump. If you should keep
gas in the tank why have I not read about it in any mechanics books or
owners manuals?
