Diesel fuel systems,
repaired right the first time.
Precision diagnostics, repair, and calibration for diesel injectors, injection pumps, and turbochargers — backed by 25 years of hands-on experience and verified with printed bench reports on every job.
Precision you can verify
Anyone can say "good as new." We hand you the printed numbers that prove it.
25 Years of Precision
A quarter-century spent exclusively on diesel fuel systems — not a general shop that also does injectors.
Bench-Verified Results
Every unit is tested before and after repair. You get a printed report — not just our word for it.
Fast, Honest Turnaround
Most injectors and pumps are back in your hands within 1–4 days, with no inflated timelines.
OEM-Grade Components
Only precision-matched parts and factory-spec tolerances go back into every rebuild.
What we repair
Every unit is bench-tested before and after repair — printed numbers, not a guess.
Common Rail Injectors
Bosch, Delphi, Denso, Siemens/VDO — teardown, precision component replacement, spray pattern calibration.
Injection Pumps
Rotary and inline pump rebuilds, bench-calibrated delivery timing, plunger and barrel replacement.
Turbochargers
Cartridge replacement, rotor balancing, actuator and VNT geometry repair.
Bench Diagnostics
Injector and pump testing on our EPS619 bench with a printed report of pressure, flow, and spray shape.
Fuel System Cleaning
Ultrasonic cleaning of injectors and rails, carbon removal without pulling the engine.
ECU Coding & Adaptation
Coding new injectors, resetting fuel trims, and clearing fuel-system fault codes.
Built for every diesel application
From daily-driver pickups to fleet accounts — the same bench standard applies.
Recent work
A look at the engines, rigs, and rebuilds that come through the shop.

What customers say
Owner-operators, fleets and independent shops that rely on bench-verified numbers.
"Sent in a set of injectors that three other shops couldn't get right. Got them back with a bench report and the truck has run clean ever since."
"We use them for our whole fleet's injection pump rebuilds. Turnaround is consistent and every unit comes back with real numbers, not a verbal 'it's fine.'"
"Mailed in a turbo cartridge from out of state. Clear communication, fair price, and it balanced out perfectly on install."
