Carb Fuel Inlet Question/Issue

Howdy all,

Got my new Q-Jet installed; 7047202 part number, Dec 1966 build, which should be right based on my car's Jan 1967 assembly date. I went to install the fuel line today, a 5/16 inch line. As you can see, that's too big. Most of the conversations I've seen have been about 5/16 versus 3/8. Obviously, 3/8 isn't the answer. My question - is something missing from the inlet on my carb? It's a rebuild I bought from a company called United Remanufacturing, and this is my first carbureted vehicle so I'm learning as I go.

Not sure how many owners, but she's mine now...

Re: Carb Fuel Inlet Question/Issue

Seems like your rebuilder didn't provide the correct fitting. 5/16" line is correct for a 327/275 hp. That fuel inlet nut doesn't look correct. It's usually a much wider nut that you will need to hold with a wrench while you tighten up the fitting. Make sure you retain that white gasket as that is what prevents leaks and the temptation to over tighten resulting in stripped or cracked inlet threads.

Quadrajet carburetor note:
7/8" inlet fittings are found on all 1965 thru 1971 automobile and truck Quadrajet carburetors, plus all year marine Quadrajet carburetors.
7/8" diameter inlet carburetors can be identified by the location of the inlet gasket, it will be located up against the tightening nut of the inlet fitting. After installation of the 7/8" inlet fitting on the carburetor, the inlet gasket is visible.
