Most transfer tanks are rated only for diesel. It's a dangerous situation for us that we have to carry numerous 5 gallon cans to be "legal". There is no reason not to allow a safe grouned transfer tank for refueling equipment. Cans tip over, cause static electric fires in pickups with bedliners, and leak on roads and hot equipment. The one positive about 5 gallon cans is they create a lot of revenue in the form of fines and tickets (wrong can, vent broke off, not tied down etc etc)upwards of $300 per can. I've had two friends hurt from static electric gas can fires, it's disgusting the state benefits in fines while putting us in danger!
