I *think* this is a physics question?
Whether we're talking about a fuel pump, or any other pump that's submersed in a liquid, I've heard that "head pressure" will make the pumping of said liquid easier which in turn means your pump in question will last longer? I've heard the deeper the pump is submerged, the easier it is to pump the liquid.
I never run my gas tank below 1/4 tank, for other reasons, but I've also heard that by doing so your fuel pump will last longer by not overheating (the gasoline lubricates and cools the pump) and by not having to work as hard to pump fuel due to head pressure.
If what I've heard is true, then maybe it's smart to try and keep your tank above 1/2 full to make the work of your fuel pump as effortless as possible?
Thoughts?
Thank you,
Ed
