The next step was to mount the new Harwood part No. 734 15-gallon fuel cell, which is perfect for the street/strip racer because it has both safety foam and a gas-gauge sending unit.

The company on Monday unveiled its first fuel-cell trucks, with a claimed 600-mile range, 15-minute refueling time, and 65-ton hauling capacity.

If you’re filling up a 15-gallon tank, you can expect to pay about 24 cents more before factoring in other statewide fees. Remember: the excise tax is only one part of what you pay.
