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

How do I find the correct replacement fuel injector for my engine?

Compare the part number on your existing injector with the number listed on the product page. Also verify the exact engine model and equipment application. If the original part number is unavailable, provide your engine and equipment details when requesting assistance.

Do these fuel injectors fit all engines from the same manufacturer?

No. Fitment depends on the specific engine model, configuration, and injector specification. Engines from the same manufacturer may use different injectors, so confirm the application listed for the individual product before ordering.

Are fuel injectors sold individually or in sets?

Both formats appear in this collection. Listings include individual injectors as well as multi-piece sets. Check each product title and description for the quantity supplied and whether the listing is for a complete set or a single injector.

Does the collection include injectors for both diesel and gasoline engines?

The collection description identifies applications for both diesel and gasoline engines. However, the visible listings are heavily represented by diesel-engine applications. Confirm the fuel type and engine application on the specific product page before purchase.
