About Fuel injector

Replacement Fuel Injectors for Diesel and Gasoline Engines

Shop replacement fuel injectors at Fab Heavy Parts for engine maintenance and equipment repairs. This collection includes individual injectors, multi-piece injector sets, and selected injector-related components for heavy equipment, agricultural machinery, industrial engines, and vehicles. Use the engine model, equipment application, and part number to narrow your search for the right fuel injector.

Fuel Injectors for Caterpillar, Cummins, Kubota, and More

Find fuel injector options for selected engines from Caterpillar, Cummins, Kubota, Isuzu, Yanmar, Mitsubishi, Deutz, Perkins, John Deere, and other manufacturers. Listed applications include Caterpillar 3116, C3.4, and C3.3B engines; Cummins 4BT and 6BT engines; Kubota D722, D902, D1105, and V2403 engines; and the Isuzu 4BD2 engine. These are examples of listed applications, not a guarantee of fit across every machine or engine variant.

Find Injectors by Part Number and Engine Application

Searching by part number can help narrow down the options. Examples listed in this collection include Caterpillar 235-5901, 314-9985, and 1W5829; Kubota 1J770-53050 and 16871-53000; and Cummins 3932123 and 3802905. Some products are sold individually, while others are listed as sets, so check the product details for the included quantity and stated engine applications.

Choose the Right Fuel Injector for Your Equipment

Fuel injectors are designed for specific fuel systems and engine configurations. Before ordering, compare the existing injector's part number and the engine's exact model and configuration with the information on the individual product page. Do not assume that injectors are interchangeable simply because the engines share a manufacturer or similar model name.

Frequently Asked Questions

Can you help me find a fuel injector if the number on my old injector doesn't match your listing?

Yes, we can help review the available replacement options. Send us the number printed or stamped on your original injector, along with the engine model and equipment details. Some product listings show multiple reference numbers, but those numbers should not be treated as interchangeable without verification. Additional engine or fuel system information may be needed to identify the correct replacement.

How do I know whether I need a common rail injector or a different type?

The correct injector depends on your engine's fuel injection system. Our fuel injector collection includes products for different diesel engine applications, including selected common rail systems. Check your engine identification and original injector part number rather than choosing by appearance alone. If you're unsure which system your engine uses, refer to its service information or provide the engine details for review.

Should I buy a single fuel injector or a complete set?

That depends on your repair requirements and the condition of the existing injectors. Our fuel injector collection includes individual injectors and multi-piece sets, so check the quantity stated on each product page. If several injectors are being replaced, confirm that the selected set contains the correct number and specification for your engine. Replacing every injector is not automatically necessary for every repair.

Is there anything I should check before installing a replacement fuel injector?

Before installation, confirm the injector's part number, application, and condition. Check whether the engine manufacturer's procedure requires specific seals, installation steps, or injector coding and calibration. These requirements vary by fuel system. Follow the appropriate service documentation, and avoid opening or testing high-pressure fuel connections without the required equipment and training.

What should I do if my engine still runs rough after replacing a fuel injector?

First, confirm that the replacement injector is correct for the engine and that any required installation, coding, or calibration procedures were completed. Continued rough running may have other causes involving fuel supply, electrical controls, engine condition, or the remaining injectors. We recommend following the engine manufacturer's diagnostic procedure or having a qualified technician inspect the system before replacing additional components.
