Ten years ago it seemed like every component for an EFI engine was different than a carbureted one, but in the last ten years those differences have gotten less and less. Computer-controlled ignitions, nitrous, and more have become so normal that even if a carburetor is on top of the engine it might have a LOT of high-tech electronics everywhere else. So it should come as no surprise that many people think you MUST have a carburetor specific fuel pump for your engine.
Don’t get me wrong, there are definitely times when a simple Holley Blue pump is all you need for a carbureted setup. But there are some times when an EFI style fuel pump could be beneficial in your carbureted car or truck. In this video from Holley you’ll learn a little bit about why this is.

Why run an EFI-style fuel pump on an engine with a carburetor? There are a whole host of reasons, including cooler fuel temperatures, more stable fuel pressure, longer pump life, and the ability to handle boost referencing, if you need it. And if you do decide to convert to EFI later on, your fuel system will be ready!
