Sec. 34. A person may seek a refund or claim a deduction for tax paid under this act on gasoline or diesel fuel that is sold tax-free by the person seeking the refund or claiming the deduction to the federal government, the state government, or a political subdivision of the state for use in a motor vehicle owned and operated or leased and operated by the federal government, state government, or a political subdivision of the state.
