Tax Incentives for Used Fuelmakers

[BRodri]

are there any tax breaks or incentives here in okie land that would help me in purchasing 2 used FMQ2.5's and if so are there any certain procedures that i need to follow to get them. also is there a discounted rate for home filling here in oklahoma. do i need to install another meter meter just to get the amount used for filling or is there a combined rate that i could get.
