I guess the avatar just isn't enough.

 

Nope. But a gas tank is a gas tank and a fuel pump is a fuel pump.

I didn't realize I needed a new Stang to enter this thread

 

its ok bone I rather have a guy that knows what hes talking about then a guys of people that havent a clue how a modern fuel tank works.

 

Lol at all the people getting confused/mad.

Particles and matter accumulates in a fuel tank over time. When you run your car till empty those particles and crap have a much easier way of getting into the pump / filters.

 

What's a fuel tank..?

 

its were babies come from!!!!

 

What kind of particles?

 

The ones that cause engine gunk and unwanted buildup. The same ones that clog filters and damage pumps. The sad reality is that our fuel is not as clean and genuine as it should be. Many times it is laced with various chemicals to stabilize its volume and hinder the effects of fuel contamination. During extraction of oil, contamination is likely to occur, and may often go unnoticed. When fuel is transported, it may also become contaminated as a secure clean can never be ensured on all surfaces it comes in contact with. The contaminates tend to fall to the bottom, and that is why running an empty tank till your car dies is not good.

 

I actually don't really care. This thread has some silly people in it...
Agree and dissagree... particles that would enter the tank are sinkers. They stay on the bottom of the tank where the pump is. So they are gonna get sucked up anyways.
I agree because floating particles would likely be introduced to the pump when the fuel level is low. But you don't get floaters in gas. Usually only sinkers

The particles are not what I would be worried about. I would worry about the pump overheating.

 

Usually the filters only capture dirt... not much more than that in fuel as far as contamination goes...

 

I've taken down literally hundreds of gas tanks. I have seen some trash in the bottom of the tank but way too big to ever get past the sock. The pump will pass smaller particles that the filter is designed to trap. Any smaller particles that can pass the filter will pass through the injectors also. The biggest issue with running a tank low is overheating the pump.

 

End of story
No more questions!
Let the thread die!!!

 

Just one more. If you don't believe Bone, believe me. Lol

 

I see nothing with your name on it? :shrug:

 

im not even a dad

 

Guess you will have to just take my word for it buddy. Or not.

 

Lessons learned from this thread:

1) Don't run out of gas/tank get empty; causes the fuel pump to overheat.
2) Lots of experts on this subject; not me for sure.
3) Folks have taste/distaste in tee shirts.
4) Gas tanks contain floaters and sinkers in the way of debris. Filter captures these.
5) Flapper in filler neck works as a sealer (like a traditional gas cap).

All in all, not a bad thread. At least for me; I learned something.

 

Fun read......now lets keep it above E.

 

So....how much time at running low fuel (less than 1/4 tank) does it take for the average fuel pump to burn out?

 

I'm not a ASE certified mechanic and never seen a gas tank opened up but I do have a 12 years old Honda Accord with 162k miles that still running good. I always fill it with gas when the low fuel light comes on and the needle is on E (hate stopping for gas). Never had a problem with the fuel pump, none. If the Mustang can't handle this then Ford did something wrong.
