they usually fly about 500 - 800 miles depending on how hard it is flown
200 miles
The external tank will empty first.
450 - 500 miles depending on how heavy your foot is ...
That would depend on the size of the fuel tank. As a go-kart is not street legal the question is a mute issue.
The answer depends on the size of the tank and the fuel efficiency of the boat as well as whether or not it has any other source of motive power.
Allmost allways add it to a full tank.
The Blackbird can carry 20 tons of fuel wich is consumed after a 2 hour flight.
A 2008 Lincoln MKZ can travel 700 miles while on a full tank of gas.
That would depend on the make, ,model, year, and engine size of the van. Also would depend on fuel tank capacity. None of which you list.
Defective fuel sending unit.
It shouldn't. You should probably replace your fuel filter (which is inside the fuel tank).
The tank should be drained before removal. The fuel must be drained into an approved container.
