Fuel Pump Burnout?
So I've read different opinions and advice to the following question? Do in-tank fuel pumps need to be submerged in fuel as lubrication? If so, I've heard never to run the tank below half because it will burn the pumps out quicker if they aren't submerged in fuel. Sounds weird, though, because I've never heard of gasoline as acting as a lubricant. Anyone know a good, honest answer?
Thanks!

Everyone else includes their truck in their .sig file so here is mine:
1996 F-150 XLT Pacific Green Metallic
Mods: Perm mounted CB with Dual Cobra antennas, 3" body lift, 31" tires, emergency lightbar, 28" air horns, and a bunch of other smaller stuff.

Fuel Pump Burnout?
I think as long as the pump does not run dry you should be ok. That may be risky below 1/4 tank. The pump pulls fuel at the bottom and pushes it out at the top. That would seem to me to cool the motor sufficiently. I have only had one pump fail, and have had many different Fords with internal pumps. The one which failed locked up because of either running dry or foreign material in the gears. The motor was fine, as it ran ok after I cleared the lockup.
