"...he has used the p2o number 2 diesel in his F550..."
Does JBI collect fuel taxes?
Diesel (IRS No. 60). If you are liable for the diesel fuel tax on removal at the terminal rack, report these gallons on line 60(a). If you are liable for the diesel fuel tax on events other than removal at the terminal rack, report these gallons on line 60(b). If you are liable for the diesel fuel tax because you have produced diesel by blending biodiesel with taxed diesel outside of the bulk transfer/terminal system, report these gallons of biodiesel on line 60(c). If you report gallons on line 60(c), do not report those gallons on line 60(b).
Multiply the total number of gallons subject to tax on lines (a), (b), and (c) by $.244 and make one entry in the tax column.
