low fuel cancels out remote start solutions?

I agree it's to idiot proof it. I would never let my tank get below a 1/4, so I have never had a problem. It strains the fuel pump under a 1/4 tank pump runs hotter. Otherwise if they didn't have it people would be complaining way more about it. Just keep your tank above 1/4 and you will be fine.
That is 100% false about it causing the fuel pump to run hotter or strain it

Easy solution……don’t let the tank run that low. Only time remote start won’t work is if the low fuel light is triggered. If I accidentally ran that low then I realize remote start won’t work. Not really a big deal and easily avoided.

Yep. I always love hearing that one. If your electric pump could overheat and burn up in a container with 20 cubic feet or so of gasoline vapor in it these things would be popping off like 1970 Pintos in a demolition derby!

How so? Unless something has changed in the past 10 years since I got my automotive degree? It wont destroy them right away but over time it will matter. I don't mean to come off as mean but I fail to see how that would be false. Even when I was in the trade it was a well known thing. My old truck with 350,000+ miles never did a fuel pump never let it go below a quarter. My dad's old truck 295,000 miles never did one. My buddy's though who did did a fuel pump once maybe twice. His had 150,000 miles. He Always ran his tank low. Like I said I don't mean to come of as a pr*** but I would like to learn why it would be false

Maybe you could explain how it damages the pump, and we can go from there.

The fuel gets low enough there isn't enough gas to cool the pump, than it will run hotter than it would if it were partially or mostly submerged. When pumps run hot they don't last as long

So how do you explain external fuel pumps?

I'm looking as to why my thinking/explanation is wrong. I was hoping you would explain. I get why you are quizzing me, I don't know it all nor did I ever admit that. I was just wanting some insight. Obviously I must wrong so please explain

The fuel flowing through the pump is what lubricates it and helps keep it cool. It doesn't have to be submerged to stay cool. Also, it's an electric pump, most electric pumps don't get submerged.

People started claiming that running the fuel tsnkmlkw causes them to fail because they had a failure right after filling the tank up from running it lower than they normally do. A coincidence isn't evidence of an issue. Maybe it was the full tank that caused the issue. Or just high mileage. I rarely fill up before the fuel light comes in, and a lot of times let the distance to empty get pretty low as well. I have never had a fuel pump die in any vehicle I have owned, and I've put hundreds of thousands of miles on vehicles.

Seems logical.
Also, these pumps don't run balls out. They are return less and only run enough to keep the fuel rail at the commanded pressure.

I always heard that pressure head was what kept the pump happy and wouldn't have to work as hard, regardless of in-tank or in-line

The tank sits below the engine. Pump has to work just as hard to push gas up to fuel rails no matter how much fuel is in the tank. These aren't old school mechanical pumps from your grandpa's days that need some gravity to help supply the fuel

Perfect thank you. That's what I was looking for. I didn't mean to get a little defensive. When someone says I am wrong and won't say why I am wrong I get a little irritated. Again though thank you for explaining that's exactly what I was looking for. Learn somehing new everyday.

I remember a toy when I was young called the verti-bird sea rescue copter. It had an actual spinning blade on it and would fly in a circle to rescue people and lift them into the styrofoam rescue ship
Man, I had one like that. I think it was attached to an aircraft carrier :)
