Petaluma drivers dealing with hard starting, surging RPMs, black smoke, or loss of power often have an injection pump problem at the root of it. Santa Rosa Diesel Injection Sales & Service brings decades of diesel fuel system experience to Petaluma, CA, with the equipment and expertise to service the pump brands found on most light- and medium-duty diesel vehicles in Sonoma County.
Is Rebuilding an Injection Pump Worth It?
Rebuilding is often worth it, restoring performance at a fraction of replacement cost. A full rebuild returns the pump to like-new condition by replacing every worn or broken component and testing the unit to OEM specifications. For Petaluma-area truck owners, farmers with ag equipment, and fleet operators, injection pump rebuild and repair services can extend the useful life of a diesel significantly while avoiding the cost of a new unit or full engine replacement.
That said, not every pump is a rebuild candidate. If testing reveals a cracked pump body or wear too severe to restore within OEM tolerances, replacement may be the smarter path. The team evaluates each unit honestly and walks you through the options before any work begins.

Our Injection Pump Rebuild Process
Every rebuild follows a structured process to ensure the finished unit meets OEM specifications before it goes back into your vehicle.
1. In-house diagnostics: The pump is placed on a test bench and evaluated for delivery rate, timing, and pressure to pinpoint the exact failure mode.
2. Complete disassembly: All sub-assemblies are fully disassembled so every internal component can be inspected individually.
3. Cleaning and inspection: Parts are cleaned and checked against manufacturer tolerances. Worn or out-of-spec parts are flagged for replacement.
4. Reassembly with OEM-spec components: The unit is rebuilt using parts that meet original manufacturer requirements.
5.
Calibration and final testing: The rebuilt pump is calibrated and bench-tested to confirm it meets OEM performance standards before return.
Most repairs are completed within 1 to 3 business days, depending on parts availability and the scope of work. Call ahead to discuss your timeline for complex overhauls or specialty applications.
