Why You Should Not Let Your Gas Tank Run Low.
Posted 10 March 2011 - 01:32 AM
Here are the problems from running your tank low:
1) Trash and impurities etc... Collect at the bottom of the tank. Running it low will suck the trash right into the system clogging the fuel filter.
2) When the tank runs low, the fuel pick tube becomes uncovered during starts and stops, and turns. The fuel pump sucking air makes it heat up. Reducing it's life.
You should only allow your tank to get as low as 1/4 tank and your fuel pump will last a long time.
Running out of fuel problems:
The fuel pump runs at high pressure for the injection system. It's RPM (How fast it runs) is actually regulated by the back pressure caused by the fuel system pressure regulator valve. When you run your car out of fuel that pressure that regulate pump speed is no longer there. So the pump runs super fast and burns itself out.
So it's best not to run out of gas. But if you find yourself in this situation. As soon as you run out of gas, don't try to start the vehicle. The tank is not going to refill itself so you have to accept what has happened. If you try to start the vehicle you risk burning the fuel pump out.
Fuel injection fuel pumps range anywhere from 50 bucks to 500 bucks. Labor can range from 150 bucks to 500 bucks. Towing would be cheaper then burning up your pump. Or tow trucks also make fuel deliveries (usually 5 gallons of gas) that are cheaper than towing.
Just thought this info might help save money for people who do not know these things.

Further, it's not that I object to professionals preforming the maintenance on my vehicles, I was just stating the fact that, when I was younger I could preform a complete tune up on my own vehicles amongst other maintenance work (replace the spark plugs and cables, fuel filter, breaks, change the oil, radiator fluid, transmission fluid and filter, rotate the tires etc...). But, due to new design features and technical specifications, tighter engine compartments, specialized tools needed, new sensor features (tire air sensors etc...) and such, it makes performing your own maintenance much more difficult, if not impossible. Added to that, is the fact that there are warranty implications as well.
So, with less hands vehicle maintenance time, the more skills are lost. The more skills lost, the more common information lost (etc...).
