69 427/435 3x2 Holley carburetor inlet nut

[Carl Z.]

What is the correct size for the fuel inlet nut? I have seen them available with 1", 7/8", 13/16" and 3/4". Also I am pretty sure they are of brass construction. Thanks for your help.

The correct size for the fuel inlet fitting (nut) on a Holley carb depends upon the carb. There were at least 5 different sizes applicable to different Holley carb list numbers. The fittings were usually of brass construction.

Thanks Joe for the info. This is for a 1969, 427/435: center carburetor is a Holley 2300C, 4055-1, 3940929. Outer carburetors are Holley 2300, 3659, 3902353. I have two different sizes on these so need to confirm correct size before I buy replacements.

On my 67 L-71, they take a 1 inch wrench and a 3/8 tube flare fitting.
