About DELCo Diesel Services

  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 thirty-sixth year of operations. Phil and David Lanham, the sons of Monk and Frances now own the company. We have been members of the Better Business Bureau since 1983 and are very proud to have an A+ rating.

  We are factory authorized service dealers 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 mat 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 technicians have well over 100 years combined experience. We are members of the Association of Diesel Specialists and participate in their nationwide warranty program.

  In addition, we provide filters and filtration systems manufactured by AC-DELCO, Baldwin, Dahl, Delphi, Lucas, Racor, Stanadyne, Fleetguard, Motorcraft, and Robert Bosch. 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 have expanded the company to include turbocharger sales and service, starter and alternator sales and service, air, gas and spring starter systems, instruments and gauges, glow plugs and controllers, radiators, intercoolers, water pumps, vacuum pumps, transfer pumps, batteries and many other related components.

  We also provide gasoline injector service utilizing the ASNU Injector Diagnostic Testing & Servicing System. We can service most multi-port and throttle body injectors.

Additionally, we sell and install diesel performance products. We represent over one hundred manufacturers. Please see the additional pages for more information. We look forward to servicing your needs.

  At 2218 S.W. 10th, east of the main building we have added our diesel pick-up service center. We are an authorized Bosch Diesel Service Center and AC-DELCO service center. We specialize in servicing your Chevrolet, Ford or Dodge diesel pickup. We utilize the latest factory diagnostic equipment and specialize in fuel and electronic systems. We are an authorized Jasper and Reviva engine and transmission dealer and installer.

  We also do business as DELCO TOOLS & EQUIPMENT, providing sales of professional mechanics tools, diagnostic equipment, refrigerant recycling equipment, air compressors, waste oil heaters, and many other related items. We are proud to represent Robinair as the service center for central and western Oklahoma.  The tool store is located at 1114 S. Agnew Ave., just south of the main building.
