Thompson Diesel - Fuel Injection and Turbocharger Specialist

Thompson Diesel was founded in 1970 in Oklahoma City by brothers Raymond and James Thompson. Our Tulsa facility opened in 1973. Raymond Thompson retired in 1992. James Thompson retired from the fuel injection business in 2011 but still remains active in Thompson Equipment & Tools, refurbishing used test stand equipment.

The current owners of the business are Al Johnston, Everett and Linda Stacy, who have more than 100 years combined experience in the fuel injection and turbocharger business.

There are two locations in Oklahoma City. Thompson Diesel, Inc. is a factory-authorized fuel injection parts and repair service center and also offers light-duty truck repair on Dodge, Ford, and Chevrolet diesel engines. Our other location, Thompson Turbo, specializes in parts and repair for natural gas turbochargers and regulators for Waukesha and Caterpillar engines.
