This is a C7 section talking about C7's lol, plus my avatar. I didn't mean to sound like I had a C6, I meant that it doesn't just hold 15-16 gal or whatever he said.
It won't, he's just making stuff up.

Fuel is what keeps the fuel pump cool. You run the tank too low repeatedly, and the pump will overheat and die. A lot of cars with the pump in the tank rely on this. Some are worse than others as far as pump life. I have no proof for the life of the C7 fuel pump, but also don't see why anyone would push the issue.

This is incredible. A very simple question which was answered in the first two responses has turned into a minor pissing contest with 20 some posts. This forum is incredible for its general irrelevance.
Maybe there should be a section within each vintage of Vette called, Straight answers to questions, no ******** opinions

If you think it's not, show proof of a car having the fuel pump burn up from being LOW on fuel, not being run empty.
Show anything from GM stating that if you run it LOW not empty, it can be a problem.
Please provide at least one shred of proof, or stop spreading BS rumors.

Do you really think "in tank" pumps create that much heat that they need EXPLOSIVE fuel to keep them cool??
So lets go on your great discovery of why in tank pumps fail.. How is that the struggling Americans that are always running on $10 of fuel are not stranded all over our roads???
Pump failure is due to the use of inferior parts with in the pump. I'm pretty sure the safety factor of over heating pumps ( That would cause a melt down and eventually a spark or two) is not even a chance.

You and your brother need to get out more....google is your friend.
(answer supplied by Al Gore...)
Yes. Fuel injected engines require higher fuel pressures than the older vehicles with carbs. Because of the work the fuel pump has to do, it gets very hot. The manufacturers put the pumps into the tank so that the fuel in the tank keeps them cool. It is for this reason that you should not run your vehicle with less than 1/4 tank of fuel. Once the fuel level drops below that level, the pump is not submerged anymore, and it then has no way to dissipate the heat. This will lead to premature failure of the pump... Usually about an $800.00 repair.

X2... Brother!! lol
There is no way they are putting in possibly "Overheating" items in the tank. I am sure they have tested for this and ran a pump until heating failure and pretty sure they concluded the time it takes to over heat far exceeds the runtime of low fuel...
Number one failure of pumps are contamination, number two is faulty connections, number three is running dry.
Now your 1/4 tank theory probably has some connection to pump failure, but not over heating... more likely hard turns or inclines exposing the pump to suck fumes instead of fuel..

Electric pump[edit]
Electric fuel pump
A piston metering pump f.e. gasoline- or additive metering pump
In many modern cars the fuel pump is usually electric and located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine. The higher gasoline pressure raises the boiling point. Placing the pump in the tank puts the component least likely to handle gasoline vapor well (the pump itself) farthest from the engine, submersed in cool liquid. Another benefit to placing the pump inside the tank is that it is less likely to start a fire. Though electrical components (such as a fuel pump) can spark and ignite fuel vapors, liquid fuel will not explode (see flammability limit) and therefore submerging the pump in the tank is one of the safest places to put it. In most cars, the fuel pump delivers a constant flow of gasoline to the engine; fuel not used is returned to the tank. This further reduces the chance of the fuel boiling, since it is never kept close to the hot engine for too long.
The ignition switch does not carry the power to the fuel pump; instead, it activates a relay which will handle the higher current load. It is common for the fuel pump relay to become oxidized and cease functioning; this is much more common than the actual fuel pump failing. Modern engines utilize solid-state control which allows the fuel pressure to be controlled via pulse-width modulation of the pump voltage. This increases the life of the pump, allows a smaller and lighter device to be used, and reduces electrical load.
Cars with electronic fuel injection have an electronic control unit (ECU) and this may be programmed with safety logic that will shut the electric fuel pump off, even if the engine is running. In the event of a collision this will prevent fuel leaking from any ruptured fuel line. Additionally, cars may have an inertia switch (usually located underneath the front passenger seat) that is "tripped" in the event of an impact, or a roll-over valve that will shut off the fuel pump in case the car rolls over.
Some ECUs may also be programmed to shut off the fuel pump if they detect low or zero oil pressure, for instance if the engine has suffered a terminal failure (with the subsequent risk of fire in the engine compartment).
The fuel sending unit assembly may be a combination of the electric fuel pump, the filter, the strainer, and the electronic device used to measure the amount of fuel in the tank via a float attached to a sensor which sends data to the dash-mounted fuel gauge. The fuel pump by itself is a relatively inexpensive part. But a mechanic at a garage might have a preference to install the entire unit assembly.
I bet you guys think the word is flat.

I'm looking for the part where it says that below 1/4 tank will burn the pump out.

You do know any fool can write a Wiki article right?
And the part you Bolded... You do know that the pump is mounted at the top of the tank and goes all the way to the bottom where the pick up is...Right? I do agree liquid fuel doesn't ignite... So when you have 1/2 tank of liquid.. What's in the other half of that tank? Oh that's right Vapor...
You Google experts need to post from a Fuel pump Manufacture that the pump will over heat with low fuel.. Then I will change my thinking, but I refuse to if you keep posting Wiki as facts..LOL
