I received my Holley 2300 sooner than expected, perfectly packaged and ready to bolt-on. Tech support gave me the guidance I needed and the conversion from an old outdated, governed carb was easily accomplished. Two Thumbs Up!

Do you know what the fuel fitting inlet size is? 1/2" or 9/16"? Or can you recommend the specific Holley fuel fitting needed. My fuel line in 5/16". Thanks.
