Don't think you can "tap" into that 2000 mile of pipe line and refuel a forklift. That pipe line is used to move items such as crude oil, natural gas, diesel fuel, ethane etc. to a refinery/distribution point some where. The end user of this "phantom" forklift" will need to have on site means to refuel their unit(s) before than can use it like they do for diesel fuel, LPG or CNG, etc. Certainly all 500 of these 16T units won't be used in the same "neighborhood".

FYI the driving distance from Seattle, Washington is 3296 miles or by 2723 miles via airplane.
