Diesel Fuel Injection Service in Yuba City & Marysville, CA | Valley Fuel Injection

Drive CA-113 south out of Yuba City and you pass through about 30 miles of exactly the thing we build our week around: rice ground, orchards, levees, irrigation risers, and equipment that has to run on a schedule set by weather rather than by anybody’s convenience. That road ends in Woodland, at our door.

Valley Fuel Injection & Turbo rebuilds diesel injection pumps and injectors on calibrated benches. Not replace. Rebuild. For Sutter and Yuba County growers that distinction is most of the point, because a large share of the equipment working this ground runs mechanical injection pumps that nobody manufactures anymore. When the pump on a 30-year-old tractor gives up, “buy a new one” is often not a sentence that ends anywhere useful. Rebuilding it is the answer, and it is a bench trade.

The Pumps Actually Sitting on Sutter County Equipment

Tractors around here are working assets, not museum pieces, and a well-kept orchard tractor from the 1980s or 1990s will outlive several pickups. These are the pumps we see from this area most often, and all of them are rebuildable:

• Stanadyne DB2 Rebuild
  The rotary pump on a huge amount of John Deere, Ford, Case and International ag iron. Probably the single most common pump on this bench.
• Delphi CAV DPA Rebuild
  Massey Ferguson, Perkins, older Ford. The classic English rotary pump.
• Delphi DP200 Rebuild
  The later Delphi rotary on newer ag platforms.
• Bosch VE Rebuild
  Kubota, Yanmar, Case, and a long list of compact and mid-size tractors.
• Inline Pump Rebuild
  Bosch A and P series, Denso, Zexel. The pumps on bigger tractors and harvesters.
• CAT 3208 Rebuild
  Irrigation pump engines, older trucks, gensets.
• CAT 3304 and 3306 Rebuild
  Ag and industrial workhorses that refuse to die.
• Mechanical Injector Testing
  Pop-off pressure and spray pattern. Cheap insurance next to a pump job.

Not sure what is on your machine? Call it in with the make, model and engine, or read us the tag on the pump, and we will tell you. If you want the long version first, we wrote it up here: tractor injection pump rebuild. We also carry pumps and injectors outright in the shop when replacing beats rebuilding.

Rebuilds are backed by our warranty: 1 year on the rebuild, 30 days on electrical and electronic components.

Why a Tractor Pump Cannot Be Fixed in a Field

Your mechanic can pull a pump. Most farm shops around Yuba City can pull a pump. That is not the hard part.

The hard part is what happens next. An injection pump is a precision fuel-metering device, and its whole job is delivering a specific quantity of fuel at a specific moment, repeatedly, for thousands of hours. Rebuilding one means disassembling it, replacing the wear parts, reassembling to tolerances measured in microns, and then putting it on a calibrated test stand and setting delivery across the full speed and load range against the manufacturer’s spec sheet. That stand, and the Bosch certification behind it, is what we have.

Without that stand, you have not rebuilt a pump. You have cleaned one and hoped.

The good news for Sutter and Yuba County: the pump travels, the tractor does not. Nobody trailers a harvester to Woodland. You pull the pump, or your farm mechanic or dealer pulls it, and it comes down CA-113 in the back of a pickup or in a box on a truck, then goes back on the machine calibrated. We do that wholesale for farm shops and dealers across both counties, so if injection is the job you send out, send it here.

Harvest Math, and the Case for Winter

Rice comes off in September and October. Almonds and walnuts run late summer into fall. Peaches and prunes have their own tight windows earlier. All of these have one thing in common: the window is set by the crop and the weather, and it does not move because your pump picked that week to quit.

Here is the honest advice, and it costs us business in September to say it: do not wait for harvest to find out.

If a machine was hard to start last fall, smoked more than it used to, lost power under load, or carries a pump with an unknown number of hours on it, that is a December, January or February job. In winter the bench has room, parts have time to arrive if your pump needs something uncommon, and nothing is rotting in the field while you wait.

Turnaround always depends on our current schedule and on parts availability for your specific pump, which is exactly why the calendar matters: in January that is a scheduling problem, and in October it is a crop problem.

Irrigation, Orchards and the Rest of the Yard

Irrigation pump engines

Flood-irrigated rice and orchard drip both depend on diesel pump engines that sit still for months and then are expected to start and run continuously. That duty cycle is hard on injection systems: fuel degrades, seals dry out, injectors gum. The failure never happens in the shed. It happens on the first hot day you need water.

Compact and orchard tractors

We are an authorized dealer for Kubota and Yanmar, which covers most of the compact diesel working the orchards and the small acreage between here and the Buttes. That means genuine parts and factory-supported service, including the newer common rail engines whose injection systems are far less forgiving of bad fuel than the mechanical pumps they replaced (this is how we test those). We are also a Delphi service point, which matters if you run Perkins or Massey, and we stock Case and New Holland injectors.

Farm trucks

The rigs hauling on CA-99, CA-20 and CA-70 come to the same bench: Ram Cummins including 5.9L VP44 pump work, Duramax, and Power Stroke from the 7.3L forward.

Talk to the Bench

Valley Fuel Injection & Turbo, Inc. has rebuilt and calibrated injection pumps on its own benches in Woodland since 1993, and is an authorized dealer for Kubota, Yanmar, Delphi and Alliant Power. The rice and orchard country north of us is about 35 minutes up CA-113.
