United Diesel Service, Inc.

Serving Your Diesel Fuel Injection Needs For Over 60 Years

For over 60 years United Diesel Service, Inc. (UDS) has been
servicing out fuel injection systems for diesel engines. Our
reputation is built on responsiveness, quality, workmanship
and reasonable prices.

Unlike other diesel service companies who subcontract a lot
of work, UDS can perform essentially all repairs in-house,
from reconditioning to calibration. Our technicians are
authorized to do factory warranty work for almost all diesel
injection systems. In addition, they are crossed-trained in all
phases of repair. We are proud of our competent and stable
workforce,they are an important part of our success.
We also provide drive service with an in-house fuel shop.
Down times to a minimum.

We offer “flat rate” or “exchange delayed” billing to minimize
engine down time.

We rebuild or exchange Cummins STC and Cummins Celect Injectors at a reasonable price.

We provide quality service, delivered promptly at competitive
rates and our work is guaranteed. We know by providing
these services we will continue to succeed. And that’s how
we’ve become one of the oldest diesel repair shops in
Southern California.
