Delco Diesel Services was founded in 1976 by D.E. “Monk” and Frances Lanham, to provide quality diesel fuel injection service at a reasonable price. That objective continues today as DELCO enters its forty-third year of operations. Phil and David Lanham, the sons of Monk and Frances now own the company. We strive to be your first choice for factory authorized service. Additionally, we have been members of the Better Business Bureau since 1983 and are very proud to have an A+ rating. We are members of the ADS (Association of Diesel Specialists – a worldwide trade association) and participate in their nationwide warranty program. We are factory authorized service dealers for Stanadyne, Robert Bosch, AMBAC, Delphi, Denso, Yanmar, Zexel, Alliant Power, Prodiesel, and Motorpal.

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 or rebuild these units. We also have exchanges available on many pumps and injectors. We have seen water contamination to diesel fuel increase dramatically over the years, this causes severe damage to the pumps and injectors. To prevent this, we recommend the use of Stanadyne or FPPF fuel treatments. We provide parts and service for Caterpillar, Cummins and Detroit Diesel fuel systems. Our technicians have well over 200 years of combined experience.
