GMC Fuel Injectors

GMC applications cover a wide mix of truck and SUV platforms, and injector fitment often varies by engine family, fuel type, and model year. Use the Make/Model/Year/Engine selector on this page to narrow the product grid to injectors intended for your specific GMC setup. Many listings include key identifiers—like OEM part numbers, connector type, and whether the injector is new or remanufactured—so you can compare options confidently. If you’re deciding between direct replacement and an upgrade path for a modified GMC truck engine, start by confirming what’s on your vehicle today and then review the injector specs shown in each listing. For deeper selection guidance, see our select the right fuel injectors resource.

GMC Fuel Injector FAQs

What should I look for on a GMC injector listing besides the year/engine filter?
After filtering by model, year, and engine, compare the details shown in the listing, including OEM part number references, whether the injector is new or remanufactured, and the connector type. Those identifiers help ensure you’re matching what your GMC uses from the factory.
Why do some GMC injector products mention multiple OEM part numbers?
A single injector design may cross-reference to multiple OEM service part numbers used across different GMC model years or engine packages. If your existing injector has a visible part number, match that number to the listing for the most confident fit.
What are Delphi or Multec-style injector connectors?
Many GM truck applications use Delphi or Multec-style connectors, and some FiveO injector listings for Chevy and GMC truck engines specify a Multec II or Delphi connector type. Before ordering, compare your current injector plug to the connector type called out in the listing to avoid a mismatch.
What does FLEX or bi-fuel mean when it appears in GMC injector listings?
Some listings indicate FLEX or bi-fuel compatibility as part of the OEM application notes. If your GMC is a flex-fuel vehicle, confirm your exact engine and fuel system configuration, then choose an injector listing that matches the application notes shown on the product.
What’s the difference between new, remanufactured, and matched set injector listings?
New typically indicates brand-new service parts, while remanufactured indicates injectors that have been restored for reuse. Some products are offered as matched sets, which can be useful when you want consistency across cylinders, while others are sold individually, so follow the quantity details shown in each listing when ordering.
