Colin breaks down of the manufacturing differences between the Edelbrock and Holley mechanical fuel pumps, specifically for the Small Block Chevy applications. When it comes to price point, the manufacturing process plays a big role, and for how important a fuel systems integrity is for the engines performance and health, it is imperative to understand these factors when choosing the right components for your carbureted fuel system needs.

Some of the manufacturing differences between the Edelbrock and Holley Mechanical Fuel Pumps that Colin points out include the inlet/outlet bore diameters, fulcrum assemblies, as well as the spring locations in the assemblies. See the contrast in manufacturing of these mechanical fuel pumps and how to decide which product is best for your small or big block applications!
