Of course. It will cause no damage at all
it depends on your vehicles gas mileage. i think really close to one fourth of a tank.
The number of miles you can drive is not dependent on the shape or material of the gas tank. The size of the tank matters, the larger the tank the farther you can drive.
Full gas tank capacity is 19.2 US Gallons. You do the math.
Possible a defective sending gauge or float inside the tank.
its in the gas tank so you will have to drop gas tank
Impossible to answer. Depends on the year, engine size, how you drive, and many other variables. My advice is when you get to 1/4 tank stop and fill up.
both sides... in the rear, under rear seats, you have to remove exhaust and drive shaft to get to it.
If you are working on a vehicle that has the gas tank on top of the motor, maybe.
Drive to a different gas station.
no
Normally under and to the rear.
Until it runs out.
