Kubota Injection Pump 1G916-51013 | Genuine Fuel Injection Pump for V2203-M Diesel Engines

This is a new, genuine Kubota fuel injection pump assembly, part number 1G916-51013, for the Kubota V2203-M-E3B diesel engine. The V2203-M is Kubota’s 2.2 liter indirect injection (E-TVCS) four cylinder, and it runs a mechanical Zexel/Denso PFR4M style inline pump. If your machine is hard to start, hunting at idle, smoking, or down on power and you have already ruled out filters, fuel supply, and air in the lines, a worn injection pump is a common failure point on high hour V2203 engines. Valley Fuel Injection is an authorized Kubota dealer and a full service diesel injection shop, so you get the correct genuine pump plus real technical support from people who work on these pumps every day.

• Kubota V2203-M-E3B (2.2L E-TVCS indirect injection diesel)

A note on accuracy: some aftermarket listings label this pump for the Kubota V3300 engine. Our research says that is a copied listing error. Part number 1G916-51013 is a V2203-M pump. Kubota built the V2203 in many variants over the years, so before you order we recommend sending us your engine model and serial number through our contact page. We will verify the exact pump your engine calls for.

Cross-Reference Part Numbers

• Zexel / Denso PFR4M 094500-8551 | interchange reported by remanufacturers for this pump
• 094500-8550 | Zexel number associated with the earlier 1G916-51010 version

If the tag on your old pump shows a different number, call us before ordering and we will cross it for you.

Frequently Asked Questions

How do I know this is the right pump for my tractor?

Check the engine model on the valve cover decal or the machine’s emissions label, then give us your machine serial number. If it is a V2203-M-E3B in one of the machines listed above, this is very likely your pump, but serial verification is the only way to be certain because Kubota revised this pump more than once. Call 530-668-0818 and we will confirm it against the Kubota parts system before you spend the money.

Is this a new genuine Kubota pump or a rebuilt unit?

This listing is for a new, genuine Kubota injection pump assembly supplied through our authorized Kubota dealer channel. See our Kubota engine sales, parts, and service page for the full range of what we stock. As a complete injection shop we can also test, calibrate, or rebuild your existing pump if that fits your budget better; learn more on our diesel fuel injection services page.

My old pump is marked 1G916-51010 or 1G916-51012. Can I use this one?

In most cases yes. Parts listings show 1G916-51013 as the current version in the 1G916-51010 to 1G916-51012 to 1G916-51013 chain, and it is the number Kubota sells today. We still recommend confirming with your engine serial number, which takes us just a few minutes.

Why do I see this pump cheaper online?
Short answer: it is usually not the same part — and a pump failure does not stay in the pump. Read why ↓

Search any OE number and eBay, Amazon and a dozen storefronts will show it well under dealer cost, sold by outfits with no name, no address and no phone number. We lose business to those listings every week — and we see a lot of them come back through our shop. Here is what is actually different.

• The part number proves nothing on its own. Counterfeit injectors and pumps are stamped with the same OE numbers as the real thing, in housings cast to look identical. The number in the listing title tells you what the seller claims it is, not what came off an OE line.
• “Remanufactured” is not a regulated word. A genuine reman unit is stripped to bare components, has its wear parts replaced — nozzle, plunger and barrel, solenoid, seals — and is then run on a calibration bench until it meets the original flow and response spec. A cheap one is very often cleaned, resealed, painted and shipped. Both get called remanufactured.
• No full teardown, so no idea what is worn. A proper rebuild means the unit comes apart completely and every part gets inspected and measured against spec — not just the ones that are obviously bad. Skip the teardown and you are reusing worn internals inside a freshly painted housing. It will run on the truck. It will not last.
• No factory-spec bench load testing. A unit is not finished until it has been run under load on a test bench and made its numbers across the range, not just at one easy point. That bench time is most of what you are paying for. Sellers working on price cut it first, because nobody can see it in a photo.
• The warranty has to be honored by someone. Everything we remanufacture in house carries a one-year warranty, with 30 days on electrical components. Parts we supply as an authorized dealer carry the manufacturer’s own warranty. Either way you call us, a real shop in California, and we sort it out. A marketplace warranty usually means shipping the part overseas at your own cost and hoping for a reply.
• No core program. We credit your rebuildable core back in full. Discount sellers generally will not take one, so the gap narrows the moment you account for the core you are now stuck holding.
• A pump failure does not stay in the pump. When a high-pressure pump comes apart it sends metal downstream through the rails, the lines and every injector. That is the whole reason fuel contamination kits exist. A pump that was never tested to spec is the cheapest possible way to buy that repair.

We are an authorized dealer and a working fuel-injection shop — we have been rebuilding and testing this hardware in Woodland since 1993, and the people who answer the phone are the people who run the benches. Not sure this is the right part for your engine? Call us with your serial number before you order and we will confirm it. Send your rebuildable core back and the core charge is refunded. And if a price somewhere else looks too good, call 530-668-0818 and we will tell you straight whether it is a deal or a problem.
