Delphi DP200 & DP210 Injection Pump Rebuild Service
The Delphi DP200, and its electronically governed sibling the DP210, are rotary distributor diesel injection pumps that succeeded the well-known DPA, and Valley Fuel Injection has been rebuilding both to factory standard for years. You will find them on John Deere and Perkins agricultural and industrial engines, along with Caterpillar 3054 and Cummins B-series applications. When a DP200 or DP210 wears out, rebuilding your own core is almost always faster, cheaper, and better than chasing down a discontinued pump that may no longer be manufactured. We rebuild your core and bench-calibrate it to factory specification, so you get a pump matched to your engine instead of a generic replacement or an imported knockoff.
The Valley Fuel Injection Difference
We are a rare breed. There are not many shops left in the country with the training, the certification, and the test equipment to rebuild a diesel injection pump to factory standard, and fewer still that do it at our level. This is not a cheap imported knockoff and it is not a throw-together seal-kit job. It is a genuine, certified, factory-spec rebuild, done by hand and proven on the bench before it ever leaves the building.
When you send a pump to Valley Fuel Injection, it is rebuilt by licensed, factory-certified diesel technicians, to the same standard the pump held the day it left the factory, and it is backed by a real warranty. That is the whole point of what we do.

Common Delphi DP200 and DP210 Models We Rebuild
The DP200 and DP210 family spans hundreds of part numbers. These are some of the specific Delphi models that regularly come across our bench, most on John Deere, Perkins, and CAT agricultural and industrial engines:
8920 series: 8920A450G, 8920A490G, 8920A970G
8922 & 8923 series: 8922A230G, 8923A050G, 8923A160G, 8923A560W

Do not see your exact number? It does not matter. We rebuild every DP200 and DP210 variant Delphi ever built. Read the model number off the tag on your pump, call 530-668-0818, and we will confirm it and quote your rebuild.
Any product image shown is a representative example. Your DP200 or DP210 pump may differ in appearance by application, year, and configuration. We rebuild your exact pump to its factory specification.
Signs Your DP200 Needs a Rebuild
- Hard starting, no-start, or long cranking when the engine is cold or hot
- Loss of power, sluggish throttle response, or a noticeable drop in top speed
- Hunting, surging, or an idle that will not settle down
- Erratic governor behavior, whether the pump uses a mechanical or an electronic governor
- Diesel fuel leaking from the pump housing, the throttle shaft, or the top cover
- Timing faults, advance problems, excessive smoke, or rough running
How We Rebuild Your DP200
A Valley Fuel Injection rebuild is not a seal kit and a coat of paint. Every pump is torn completely down and built back to factory standard, one measured part at a time:
- Complete teardown and inspection. We disassemble the entire pump and inspect every single component against Delphi factory wear limits. Nothing is reused on assumption.
- Deep cleaning. Every part is ultrasonically and thoroughly cleaned so we are building on bare, spotless metal, not old varnish and debris.
- Factory-certified replacement parts. Transfer pump, cam and rollers, delivery valves, drive components, and a complete overhaul seal kit for the DP200/DP210. We replace what needs replacing with genuine factory-certified components, never cheap generic substitutes.
- Hydraulic head, governor, and advance service. The hydraulic head and rotor, the governor (mechanical or electronic), and the automatic timing advance are serviced and set so fuel delivery is even across every cylinder.
- Calibration and testing on real machines. The finished pump is mounted on a professional, computer-controlled test bench and calibrated to your pump’s exact DP200/DP210 factory specification sheet. We set transfer pressure, timing advance, and fuel delivery at every point on the governor curve and prove it before it ships.
That final step is what separates a real rebuild from a parts swap. Anyone can bolt in a seal kit. Very few shops can put your pump on a bench, calibrate it to spec, and stand behind the result.
Our Warranty
We control every step of the rebuild, so we stand behind it. Every pump and injector we rebuild carries a 1-year warranty. Electrical and electronic components are warrantied for 30 days. A healthy lift pump and clean, water-free fuel are essential to pump life, so we recommend fresh fuel filters at installation to protect your rebuild.
What a DP200 Rebuild Costs
Typical Rebuild Cost
$1,350 to $1,950 typical range
Most Delphi DP200 and DP210 rebuilds land between $1,350 and $1,950, with a typical rebuild around $1,650. These are real figures from our recent DP200 and DP210 jobs, not markup guesses. Pumps with heavier wear, or that need a new hydraulic head, run higher. Because every rebuild is priced on your pump’s actual condition, we give you a firm quote after inspection, before any work begins.
Prices above cover the service and parts. Any applicable sales tax, plus shipping and small shop fees (such as a hazardous-waste disposal fee), are added at invoicing, so your quote reflects the full out-the-door number before any work begins. Buying tax-exempt? Qualifying diesel repair shops, fleets, farms, and agricultural operations can purchase tax-free. Set up tax-exempt purchasing by submitting your resale or exemption certificate once, and every qualifying order is tax-free going forward.
How It Works · Call for Pricing and Availability
Because every DP200 or DP210 rebuild is done on your own core, pricing depends on the pump’s condition and the parts it needs, so we quote each job individually. Here is the process:
- Call us with the number on your pump so we can confirm it is a DP200 or DP210 and talk through your symptoms.
- Ship the pump to us or drop it off. We tear it down, inspect it, and give you a firm quote before any work begins.
- We rebuild and bench-calibrate the pump, then return it ready to install, backed by our warranty.

Frequently Asked Questions
How much does a Delphi DP200 rebuild cost?
Most Delphi DP200 and DP210 rebuilds run between $1,350 and $1,950, with a typical rebuild around $1,650. Pumps with heavier wear, or that need a new hydraulic head, can run higher. Pricing depends on the condition of your pump and the parts it needs, so we give you a firm quote after inspection, before any work begins. Call 530-668-0818 for current pricing.
Do I send you my pump, or do you have one in stock?
This is a rebuild service for your own core. You ship us your pump or bring it in, we rebuild and recalibrate it, and we send it back matched to your engine. Rebuilding your core is usually faster and less expensive than sourcing a new pump, and many DP200 and DP210 pumps are no longer manufactured.
How long does a rebuild take?
Turnaround depends on our current shop schedule and parts availability for your specific pump. We give you an honest timeline when we quote the job. If you are down and need a fast turnaround, tell us when you call and we will do our best to prioritize it.
What warranty comes with the rebuild?
Every pump and injector we rebuild carries a 1-year warranty. Electrical and electronic components are warrantied for 30 days. We control every step of the rebuild in-house, from teardown to final bench calibration, which is why we can stand behind it. A healthy lift pump and clean, water-free fuel are essential to pump longevity, so we recommend fresh fuel filters at installation to protect your rebuild.
My pump number is not on your list. Can you still rebuild it?
Almost certainly. The DP200 and DP210 were fitted to far more equipment than we can list here. If the pump carries a Delphi DP200 or DP210 tag, we can rebuild it. Call 530-668-0818 with the number stamped on the pump and we will confirm.
Can I ship my pump to you from out of state?
Yes. We rebuild pumps for customers nationwide. Remove the pump, pack it securely, and ship it to us. We inspect it, quote the rebuild, and return it ready to install.
