About Fuel injection pump

Diesel Fuel Injection Pumps for Heavy Equipment

Find a replacement fuel injection pump for your diesel engine at FAB Heavy Parts. This collection includes fuel injection pumps and pump assemblies for selected construction equipment, excavators, loaders, agricultural tractors, utility vehicles, and commercial trucks. Search by part number, engine model, or equipment application to narrow your options for engine repair or replacement.

Injection Pumps for Cummins, Kubota, Isuzu, and More

Explore fuel injection pump listings for selected Cummins engines, including the 6C8.3, ISC, ISL, N14, and NT855 families. The collection also includes pumps for Kubota engines such as the D905, D1005, D1105, D1305, and V3800, as well as selected Isuzu, Deutz, Caterpillar, Bobcat/Doosan, and other applications.

For example, the collection lists a pump assembly under Kubota part number 16032-51013 for specified D-series engines. It also lists Caterpillar pump 436-1091 for selected C3.3B applications. These examples refer to specific product listings and should not be treated as universal fitment across all engines from the same manufacturer.

Choose the Correct Fuel Injection Pump

A fuel injection pump meters and delivers fuel to the engine’s injection system at the required pressure and timing. The correct replacement depends on the engine’s fuel system design, pump configuration, and exact application.

Before ordering, compare the part number on your existing pump with the listing. Confirm the engine model and version, equipment model, and relevant serial or configuration details where available. Check whether the listing is for a complete injection pump assembly or a particular pump component. Do not assume that pumps for similar engine models are interchangeable.

Product condition can also vary. Some listings identify new aftermarket replacements, while others offer remanufactured and new aftermarket options. Review the specific product page to understand the available variant and included components.

Frequently Asked Questions

How do I know which fuel injection pump fits my engine?

Please start with the part number on your existing pump and compare it with the replacement numbers on the product page. Your engine model and equipment model are also helpful, especially when a pump has several listed applications. If you are still unsure, please send us the part number and equipment details through our Request a Quote page, and we can review the information available for the replacement fuel injection pump.

What's the difference between a fuel pump and a fuel transfer pump?

The terms can refer to different functions within a fuel system. A fuel transfer pump moves fuel between parts of the system, while other pumps may supply fuel at the pressure and flow required by a particular engine or injection system. Please check the product description and your equipment's service documentation to confirm which type you need.

Are fuel injection pumps available in new aftermarket and remanufactured conditions?

Yes. The collection includes listings with different condition options. For example, the Kubota 16032-51013 pump assembly listing offers remanufactured and new aftermarket variants. Availability and condition should be confirmed on the individual product page.

Can I replace my injection pump using only the engine model?

The engine model is a useful starting point, but it may not be enough to identify the correct pump. Different engine versions or fuel-system configurations can use different pumps. Compare the part number and application details, and use serial or configuration information where applicable.

Should fuel injectors be replaced when replacing a fuel injection pump?

Not automatically. The need to replace injectors depends on the diagnosed fault, contamination, wear, and the engine manufacturer’s service procedure. Inspect and test related fuel-system components as appropriate before deciding which parts need replacement.
