So, you need a new mechanical fuel pump for your Small Block Chevy (SBC) engine? Awesome! This guide helps you choose the right one. Let’s get started.
Key Features to Look For
You want a fuel pump that works well. Look for these things:
- Flow Rate: How much fuel can it pump? Get one that matches your engine’s needs. More power means more fuel.

- Body Material: Aluminum is a common choice. It’s strong and lightweight. Steel is another option, but it can rust.
