In 1961 Tuthill purchased Ossian Engineering Company and transitioned it to the name of Tuthill Transfer Systems. The red pump has long been known as the pump from Ft. Wayne, Indiana and customer demand required Tuthill to grow. In 2020, Tuthill expanded its production of Fill-Rite fuel transfer pumps by opening a second manufacturing facility in Lenexa, Kansas. This location complements the operations in Ft. Wayne where not only Fill-Rite products are designed and manufactured, but so are Precision meters and Sotera chemical transfer pumps.
