Hi:

You have a Holley Red pump. They are internally pressure regulated at about 7 psi, so you won't need a pressure regulator. That's all you need to know, you can order the same pump, just specify Holley Red, you don't need a part number. They are noisy, but I have no experience with any others, and to fit another pump may require adding a fuel pressure regulator.

Cheers!
