On all my vehicles I usually start a folder with information I gather over time from forums or experience. Since we are talking about the Holley 2300 series of carburetor here is the number for the fitting that adapts the original fitting from the stock carb fuel line to the Holley. Fitting to fit Holley 2300 series carburetor for fuel, inverted flare to pipe, BQ248.

One other thing, on my hard to start Willys car after sitting for a long time, starting became really easy after I installed a check valve from Summit racing in the fuel line close to the carb, from then on it always started right away as the gas never had a chance to escape from the line. When the pump started it was always primed.
