The 767 glides about 30 miles for 10,000 feet depending on speed as do most jet airliners. If you slow up to a bit below 250 knots you will do a bit better as you get closer to your optimum lift drag. So if you run out of gas at say 35,000 feet you can glide about a 100 n. miles give or take a bit. These aircraft are all good gliders they just do it a bit faster than your average glider.
If the fuel guages are not working you can go as there is an MEL (Minimum Equipment List) on all large airplanes. Usually it will have you drip the tanks. You go under the wing and drop down a tube that goes up into the tank. When fuel starts to run out you note the depth reading on the stick. This can be converted into gallons, liters or pounds from a table carried on board, the slope of the aircraft is taken into effect and you usually take a bit of extra fuel just in case. The 767 was brand new and there was some confusion at the time. Boeing supplied the aircraft as imperial or metric and therefore the confusion.
The pilot retired from Air Canada a number of years ago at age 60 I think.
