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?

I don't push it very far in mine. I do know that it's about a 14 gallon
tank, and when I filled it the one time right after the light came on,
I put in 11.5 gallons. That meanst I had 2.5 gallons, enough for around
40-60 gallons give or take, depending on how hard you drive and how
well you've taken care of it.
