# Diesel Injection Pump & Injector Repair — Diesel Control Technicians

**Diesel Control Technicians, Inc.** specializes in diesel fuel-injection component identification, testing, evaluation, repair, rebuilding and calibration where supported. The team has **190 years of combined experience** (not 190 years in business). Customers nationwide can ask about approved mail-in component service.

## Mail-in service: easy as 1, 2, 3

1. **Tell us about it.** Share your pump/injector part number, equipment and symptoms.
2. **Send it our way.** DCT first reviews eligibility and supplies the approved receiving address and instructions. Do not ship without approval.
3. **We take it from there.** DCT evaluates supported components, explains options and asks for work authorization before additional repairs.
