Diesel Fuel Injection Service in Sacramento, CA | Valley Fuel Injection

Valley Fuel Injection & Turbo is Sacramento’s nearest Bosch-certified diesel fuel injection specialist — located just 20 minutes northwest in Woodland, CA. We provide expert diesel injector testing, repair, remanufacturing, and parts sales to truck owners, fleets, farms, and shops throughout the greater Sacramento area.

If you’re dealing with injector problems, a failing fuel pump, turbo issues, or any diesel fuel injection concern in Sacramento, Natomas, Arden-Arcade, Rancho Cordova, Citrus Heights, or anywhere in Sacramento County — we’re the closest specialized facility with the Bosch-certified equipment and expertise to diagnose and fix it right the first time.

Why Sacramento Diesel Owners Choose Valley Fuel Injection

Sacramento is surrounded by shops that work on diesel trucks. But there’s a critical difference between a general mechanic who can change injectors and a Bosch-certified diesel fuel injection center that can actually test, diagnose, and remanufacture injection components in-house.

Most shops troubleshoot diesel fuel injection problems by replacing parts until the problem goes away. That’s expensive guesswork. At Valley Fuel Injection, we put your injectors on a calibrated Bosch test bench and measure exactly what’s happening — spray pattern, flow rate, return volume, electrical response. You get a definitive diagnosis, not an educated guess.

Here’s what sets us apart from every general diesel shop in Sacramento:

• Bosch-Certified Diesel Center — Factory-trained technicians with Bosch-authorized test equipment. This certification matters because it means we test and rebuild to OEM specifications, not approximations.
• In-House Injector Testing & Remanufacturing — We don’t send your injectors out to a third party. Testing, diagnosis, rebuilding, and retesting all happen under one roof in our Woodland facility.
• Kubota & Yanmar Authorized Dealer — Factory parts and service for agricultural and industrial engines that Sacramento-area farms and operations depend on.
• Alliant Power & Delphi Authorized Dealer — Genuine OEM parts from multiple manufacturers means we can service virtually any diesel platform.
• 5+ Decades of Diesel Injection Experience — Valley Fuel Injection has been specializing exclusively in diesel fuel injection since day one. This isn’t a sideline — it’s all we do.

Diesel Fuel Injection Services for Sacramento

Injector Testing & Diagnosis

Whether you’re a truck owner trying to figure out why your Cummins is blowing smoke, or a Sacramento shop that needs injectors tested for a customer’s truck, we provide professional bench testing on calibrated Bosch equipment. We test common rail, HEUI, unit injectors, and mechanical injectors for all major platforms. See how we test injectors →

Injector Remanufacturing & Sales

We carry remanufactured and new diesel injectors for Cummins, Duramax, Powerstroke, Kubota, Yanmar, Komatsu, Case, and more. Every remanufactured injector is rebuilt in-house and bench-tested before it ships. Sacramento customers can pick up same-day from our Woodland shop or have them delivered.

Fuel Injection Pump Service

From VP44 pumps on 5.9 Cummins trucks to CP3 and CP4 high-pressure pumps on modern common rail engines, we test, rebuild, and sell injection pumps. If your Sacramento truck is losing power, hard starting, or throwing fuel pressure codes, the pump is a prime suspect — and we have the equipment to test it definitively.

Common Rail System Diagnosis & Repair

Modern diesels run common rail injection systems operating at 23,000–29,000+ PSI. Diagnosing problems in these systems requires specialized equipment and training that most Sacramento shops simply don’t have. We do. Learn more about our common rail services →

Turbocharger Service

Turbo problems often show up alongside injection issues — and vice versa. We diagnose and service turbochargers in-house, so if your diesel has both a turbo and injection concern, we can handle it all in one visit. Turbocharger service details →

Getting to Valley Fuel Injection from Sacramento

Sacramento’s Diesel Landscape

Sacramento County has a massive diesel footprint. Between the agricultural operations throughout the Sacramento Valley, the Port of Sacramento and its associated trucking, the construction boom in Natomas, Elk Grove, and Rancho Cordova, government fleet vehicles, and the thousands of diesel pickup owners who use their trucks for both work and daily driving — the demand for quality diesel fuel injection service is enormous.

Despite that demand, there’s no Bosch-certified diesel fuel injection center in Sacramento proper. Valley Fuel Injection in Woodland fills that gap, providing Sacramento with access to factory-level diesel injection testing and repair that would otherwise require a trip to the Bay Area or beyond.

We work with shops throughout Sacramento as a diesel injection testing and parts resource. If you’re a Sacramento-area shop that encounters diesel fuel injection problems beyond your diagnostic capability, we offer:

• Wholesale injector and pump testing — Send your customer’s injectors to us, we test and report back with results
