Where We Know Your Diesel

At Diesel Specialties we have been working on diesel fuel systems for over 60 years. We are factory trained and authorized to work on Robert Bosch, Delphi, Stanadyne, Zexel and Ambac fuel systems. We are also factory authorized on Garrett and BorgWarner (Schwitzer) turbochargers. We use up to date equipment to calibrate your pump accurately for the best performance possible. We have one of the largest inventories of exchange pumps, turbo’s and nozzles in the country. 

Why wait while your pump is being rebuilt when you can exchange it and reduce your downtime.
