Over 46 years ago, Gateway Diesel started as a small family-owned and operated business. After years of hard work and professionalism, Gateway Diesel has grown to become a successful company with a great reputation under the same family name.

We are located at the intersections of Rt. 366 and Rt. 380 in New Kensington, PA with salesmen covering the Western PA, Eastern Ohio, and Northern West Virginia area. Our shop is an authorized service dealer for American Bosch, Delphi, Denso, Robert Bosch, Stanadyne, and Zexel.  

In addition, we have the Common Rail Injector Test Stand that is used to test Duramax, Dodge, Denso, Siemens, Mercedes, Delphi, and Bosch Injectors.* We also service a wide variety of Turbochargers such as: Garrett, Cummins Turbo Tech, IHI, and Borg-Warner. 

Our technicians are certified by fuel pump manufacturers. We also have a drive-in service bay to pull and test injectors, fuel pumps, and turbos from smaller vehicles.
