Off road diesel at reservation?

Does anybody know if they have off road diesel at the Indian Reservation in Lewiston? I have a buddy doing work right there and he’s thinking he can just get his fuel there to run his equipment(dozers, etc…) and would rather just get it there instead of bringing his transfer tank with him. If so, which place, places had it?

They should, I have it at the rez near me. if its red its off road.

Yes they do but in all honesty I cant remember for the life of me how to get to the place. All I know is that its not the gas station at the bottom of Indian hill.
