silly question but which of these fuses "might" belong to the fuel pump

Start at the fuel pump and trace the wire back to the battery.

That's the only way to know.

You could always disconnect and plug the outlet from the pump to the carb / EFI

Thanks for the info. There's no easy way to trace the fuel pump wire from the tank to the battery as it's all bundled, wrapped and tied with a lot of other wires. I'm running a Holley Sniper so unplugging the harness should do the trick. I should have thought of that first.

Edit: I looked on Holley's website and found the wiring diagram. The "blue" wire connects to the fuel pump. I was able to trace it to where it comes out of the harness, and plugs into the system. It was a simple matter to unplug it. Thanks again for your suggestion! I feel like an idiot for not thinking along these lines!
