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.

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

• 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.
