Having trouble getting fuel injection work done on older units? We service the older IH MD Farmall tractors, the super MD, the 400 and the 450 D tractors. We also service the older American Bosch pumps that the old 400 and the 800 Case tractors use. We are one of the few shops that can service such equipment. We can repair your own unit or supply you with an exchange. Give us a try the next time you need service!!
