Welcome to DELCo. Diesel Services, Inc.

Delco Diesel Services, Inc. in Oklahoma City, OK is a factory authorized service dealer for Stanadyne, Robert Bosch, AMBAC, Delphi, Denso, Yanmar, Zexel, Alliant Power, Prodiesel, Motorpal and Governors America Corp. These companies supply the fuel systems and electronic control systems for almost every diesel engine manufacturer. Many of the fuel systems continue to be serviced for fifty or more years, so your injection pump or injectors may have other names on them, such as Roosa Master, American Bosch, United Technologies, Lucas, CAV, Simms, Nippondenso, Diesel Kiki, Minimec or Bryce. If parts are still available, we can service these units. We also have exchanges available on many pumps and injectors. We provide parts and service for Caterpillar, Cummins and Detroit Diesel fuel systems. Our company has been in business since 1976 and our technicians have well over 100 years combined experience. We are members of the ADS (Association of Diesel Specialists) and participate in their nationwide warranty program.
