Is it true that keeping your car gas tank 1/2 full makes the fuel system last longer?

Fuel injected motors rely on proper fuel pressure. Partially plugged fuel filters ruin more electric fuel pumps than any other reason. The amount of fuel in the tank has nothing to do with the fuel system.

Yes it is true. And running out will suck the bottom of the tank dregs into the system.

Changing the fuel filter after several years is good too.

Modern cars circulate the fuel to the engine and back to the tank.

I've had my fuel pump run quieter after the filter was changed.

In very hot weather, I imagine being fully submerged in fuel may cool the pump.

There is less condensation inside the tank when the empty space is smaller.

Less sloshing around puts less wear and tear on the fuel level float and sender device.

It doesn't cost any more to go from full to half.

Running out of fuel at the worst time and place could cost you money.

Like a bridge, a tunnel, or far from a station.

How would that be true? No matter how full your gas tank is. If your driving 50 miles your using 50 miles worth of gas. But I can understand if the weight of all that puts stress on the pump when it calls for more gas, but fuel pumps are so advanced that doesn't have an affect. Bottom Line. I wouldent Think so.

the engine will run approximately 2-4 days. vehicle battery will final approximately 2 days after the engine quits with one gentle on. I would not rarely make any difference what vehicle you have so some distance as gas is going because of the fact each vehicle/truck is made to flow approximately 3 hundred-4 hundred miles on a tank. effective, some don't get very solid mileage yet then they have better gas tanks.

I suppose so. I heard the same thing. You shouldn't let the fuel get down to fumes where the light comes on. I try not to, but sometimes I do.

well...what really matters is the fuel pressure and how much you idle your car....

but thats just my opinion.

maybe, the only way to test it is my doing the experiment yourself, and read how much miles, at what rpm you drive.

False.

What a bunch of crap. Where do these people come from.
