A Mechanical Legacy

Nestled in the heart of Texas, with roots dating back to 1960 in Corpus Christi, TX, Diesel Engine & Injection is a diesel engine repair shop with a cross-generational legacy. Back in 1960, the founder's father rolled up his sleeves and opened the doors in Corpus Christi, dedicating the shop to all things mechanical. Fast forward, and we've evolved into a service center, engine supplier, and fuel injection specialist, offering genuine parts from renowned manufacturers like Cummins, Deutz, Isuzu Industrial, John Deere, and more.

We cater each and every service to the needs of our customers with a personalized touch. No long waits, no automated responses — just real people ready to provide solutions to your problems. Whether it's generator repair, light tower repair, diesel engine repair, or fuel system repair, we're where the quality starts.
