The person claiming the refund may present to the Department of Transportation a statement of the claim and be allowed a refund as follows:

(a) For fuel used in pumping aircraft fuel, motor vehicle fuel, fuel or heating oils or other petroleum products by a power take-off unit on a delivery truck, refund shall be allowed claimant for tax paid on fuel purchased at the rate of three-fourths of one gallon for each 1,000 gallons of petroleum products delivered.

(3) When a person purchases and uses motor vehicle fuel in a vehicle equipped with a power take-off unit, a refund may be claimed for fuel used to operate the power take-off unit provided the vehicle is equipped with a metering device approved by the department and designed to operate only while the vehicle is stationary and the parking brake is engaged; the quantity of fuel measured by the metering device shall be presumed to be the quantity of fuel consumed by the operation of the power take-off unit.

(4) Before any such refund may be granted, the person claiming such refund must present to the department a statement, accompanied by the original invoices, or reasonable facsimiles approved by the department, showing such purchases; provided that in lieu of original invoices or facsimiles, refunds submitted under subsection (1)(d) of this section shall be accompanied by information showing source of the fuel used and evidence of payment of tax to the state in which the fuel was used. The statement shall be made over the signature of the claimant, and shall state the total amount of such fuel for which the claimant is entitled to be reimbursed under subsection (1) of this section. The department upon the presentation of the statement and invoices or facsimiles, or other required documents, shall cause to be repaid to the claimant from the taxes collected on motor vehicle fuel such taxes so paid by the claimant.
