Diesel Injection Pump & Injector Rebuild Service | Mail-In, Nationwide

Valley Fuel Injection & Turbo rebuilds diesel injection pumps and injectors for customers in all 50 states. Ship us your pump or injectors from anywhere, we tear them down, rebuild them to factory specification on our own Bosch-authorized test benches in Woodland, California, and ship them back ready to install with a 12-month, unlimited-mileage warranty. We have been doing exactly this since 1993.

Get Started: Tell Us About Your Pump

Not sure whether we rebuild your pump, or ready to get the ball rolling? Send us the details below to start the process. We will confirm we can rebuild it, answer your questions, and walk you through shipping it in. We do not quote from this form. Every rebuild is priced on the actual condition of your pump, so we give you a firm number after we inspect it, with no obligation. Only your email and a short description are required.

Looking for “injection pump rebuild near me”? Here is how that works

Most people searching for a diesel injection pump repair shop near them find out the same thing: the few shops that still do this work at a factory level are not around the corner. That is why the majority of the pumps and injectors on our bench arrive by UPS from other states. Being far from Woodland, California does not change the work or the warranty. In the lower 48 it adds a couple of days of ground transit each way, and we tell you the realistic timeline before you ship.

• Nationwide by mail: UPS, FedEx or USPS ground from anywhere in the country. Most of the Mountain West and Pacific Northwest reaches us in two to three days. See our Utah & Mountain West rebuild page for transit specifics.
• Northern California & Nevada: Drop off at the shop in Woodland, ten minutes off I-5 north of Sacramento, Monday through Friday. We also serve Sacramento, Stockton, Redding and Reno.
• Bay Area: One courier day each way. Details on the Bay Area injection pump rebuild page.

Whichever way it gets here, the process is the same: inspection, a firm quote, your approval, the rebuild, calibration on the bench, and a tracked shipment back.

Sending a pump or injectors from Alaska or Hawaii

We take mail-in rebuild and injector testing work from Alaska and Hawaii. Call (530) 668-0818 before you ship. We will confirm we rebuild your unit and go over how to send it from your address.

You send your own pump or injectors, so there is no core charge. The warranty is the same as for every customer: 12 months, unlimited mileage, with 30 days on electrical and electronic components.

We answer the phone Monday through Thursday, 7:00 AM to 4:30 PM, and Friday 7:00 AM to 4:00 PM, Pacific time. Most of Alaska is one hour behind us. Hawaii is two or three hours behind us, depending on the time of year.

Buying parts instead of sending a unit in? Injectors, pumps, turbos and Kubota parts for both states are on our Alaska and Hawaii page.

Pumps and Injectors We Rebuild

We rebuild the full range of mechanical and electronic diesel injection pumps, plus diesel injectors of nearly every type. Not sure your unit is on the list? It very likely is, so call 530-668-0818 and ask. Each service below has its own page with more detail on that pump family.

Want a faster option for a popular electronic unit? Several pumps and injectors are stocked as ready-to-install exchange parts, so you order the reman unit and send your core back afterward instead of waiting on a rebuild. That covers Dodge VP44 pumps, Bosch CP3 and CP4 high-pressure pumps, and Cummins common-rail injectors. See the exchange program for how that works, or browse all rebuild services. Trying to diagnose first? Our guides on VP44 failure symptoms and the P7100 vs VP44 5.9L Cummins comparison are a good place to start.

How to Ship Your Injection Pump

Step 1: Call or send an inquiry first

Call 530-668-0818 (Monday through Thursday, 7:00 AM to 4:30 PM PST, and Friday until 4:00 PM) or use the form at the top of this page. Have your pump’s make, model, and the number stamped on the tag handy if you can find it. We will confirm we can rebuild it and that we are expecting it.

Step 2: Pack it safely

A diesel injection pump is heavy and precise. Pack it so it arrives the way it left you:

• Drain the fuel and cap the inlet and outlet ports (the red or plastic caps if you still have them) so fuel does not leak in transit.
• Protect the drive shaft, the electrical connectors, and any solenoids. Wrap the whole pump in bubble wrap or foam.
• Use a sturdy, correctly sized box with at least two inches of padding on every side. The pump should not shift when you shake the box.
• Put a note inside with your name, phone number, email, and a short description of the problem or what you need done. If we talked on the phone, reference that.
• Keep a photo of the pump and its tag for your own records before you box it up.

Step 3: Ship it to us

Send your pump, with tracking and insurance, to the boxed Ship To address at the top of this page: Valley Fuel Injection & Turbo, Inc., 1243 E Beamer St, Suite C, Woodland, CA 95776. We accept UPS, FedEx, and USPS. We strongly recommend insuring the shipment for the value of the pump and keeping your tracking number until you have it back in hand.

What Happens After We Receive It

1. Inspection. We tear it down and inspect every component against factory wear limits to confirm what it needs.
2. Quote. We call or email you with a firm price before any work begins. Nothing is done without your approval.
3. Rebuild. We rebuild the pump with factory-certified parts and calibrate it to your pump’s exact factory specification on our test bench.
4. Return. We ship it back ready to install, backed by our warranty: 12 months, unlimited mileage on the rebuild, plus 30 days on electrical and electronic components.

Turnaround depends on our current schedule and parts availability for your specific pump, so we give you a realistic estimate when you call. If you are down and need it fast, tell us up front and we will do our best to prioritize your rebuild.

Why Ship It to Valley Fuel Injection

A mail-in rebuild is only worth it if the shop on the other end knows the pump cold. Here is what you get when you send yours to us.

What to put in the box: the pump itself, a note with your name, phone, email, and the symptoms you are chasing, and a copy of any part or tag numbers. That is all we need to get started. Core and exchange: on a mail-in rebuild we work on your own core, so there is no separate core charge, you send us the pump and we send it back. If you would rather not wait, an exchange unit ships ready to install and you return your old core afterward. Questions on either path? Reach us through the contact page or learn more about our shop.

A large share of our mail-in work now arrives from outside California. If you are shipping from the Mountain West, see our diesel injection pump rebuild service for Utah for transit times and what to expect.

Diesel Injection Pump Rebuild: Common Questions

How much does a diesel injection pump rebuild cost?

We price every rebuild on the actual condition of the pump, so we do not quote over the phone or from the form. When your pump arrives we tear it down, inspect it against factory wear limits, and call or email you a firm number before any work starts. There is no charge for the inspection if you decide not to proceed, and because a mail-in rebuild uses your own core there is no core charge on top of the rebuild.

How long does an injection pump rebuild take?

Turnaround depends on our current bench schedule and parts availability for your specific pump. We give you a realistic estimate when you call, before you ship. If the truck or machine is down and you need it back fast, say so up front and we will do what we can to prioritize it. If you cannot wait at all, ask about a ready-to-ship exchange unit for popular pumps like the VP44, CP3 and CP4.

What is covered by the warranty?

Every rebuild carries a 12-month, unlimited-mileage warranty on the rebuild itself, plus 30 days on electrical and electronic components. There is no mileage cap, so it does not matter whether the pump goes into a daily driver, a work truck or a piece of farm equipment.

Do you rebuild diesel injectors too, or only pumps?

Both. We test and rebuild common-rail injectors (Bosch, Denso, Delphi) on a common-rail bench that gives you the actual delivery and response data for each injector, and we rebuild mechanical pop-type injectors with new nozzles, pop-tested to spec. Testing a set first often means rebuilding two injectors instead of buying eight.

Which pumps do you rebuild?

Rotary and distributor pumps (Stanadyne DB2/DB4, Bosch VE, Delphi/Lucas CAV DPA, Delphi DP200), inline pumps (Bosch P7100 and A-pumps, Denso, Zexel, CAT 3208 and 3304/3306, Cummins PT), and electronic units. The full list with links to each pump family is in the section above. If yours is not listed, call, it very likely is something we do.

Do I have to be near Woodland, California?

No. Most of our rebuild work arrives by UPS from outside California. Pack the pump with the fuel drained and the ports capped, add a note with your contact details and symptoms, ship it insured with tracking, and we handle the rest. Full packing instructions are above.
