Ok here goes with what I found out. This gets hilarious. :laughing:
I called the people

that should know the answers and they did not have a clue!
1.It seems that tractor owners know more than the government and the people that or responsible for enforcing the laws. Score one for you guys.:thumbsup:
2.The DOT is more interested in pump handles color- diesel is green.
3.OSHA and Nfpa are interested in tank color. diesel is yellow
4.When I called the national DOT office they said green is for diesel. Tanks, handles and hose.
5.When I called Wa. state patrol they thought I was nuts, did not understand what I was asking until I drew them a picture, and still did not have a answer. They suggested I call the weigh station.
6.When I called the weigh station on I5, just north of Vancouver, Wa. They needed me to also draw them a picture, They finally told me it had to be an approved container for the fuel I was transporting. I asked them what constituted an approved container for diesel and they could not give me an answer. At this time I thanked them and got out of dodge cause the officer

was beginning to smoke a little from under his hat.
7.I was raised in south Texas and all of the diesel tanks at that time were green and gas was red. I moved to south west Washington 30 years ago and all of the diesel tanks around the mill I worked at and in the logging camps had a lot of green diesel tanks. So I assumed that Green was a diesel designation. So since the fine officer that are enforcing these laws on us the public do not really know or understand what color is for diesel, I will paint my tank whatever color I want. :tractor: Kubota ORANGE!
I :dance1:have had more fun and have laughed more in the last hour than in a long time. It was better than watching a Laurel and hardy film. When I get my tank done I will post a picture of it so we can stay on topic! I have learned and had fun doing it Thanks Guys!
