    I've exhausted my local possibilities and internet searches have provided little help.
    This is a 5/16 x 5/16 x 5/16 "T" any ideas?

    Did you try your local NAPA? Are you sure it's 5/16"? Pipe/tube fittings can be tricky to measure.

    Check out McMasterCarr.com.

    I should have mentioned that the end that goes into the carburetor as pictured is a male 5/16 the other two are female 5/16

    A male to male adapter should solve that issue.

    What's the problem with the original one that you need to replace it?

    I saw one of these before, so I looked and I think this is what you need. I looked at a fittings catalog and here's what I found.

    Weatherhead #1514 / Edelmann #261520 / Everco #1514. This is the piece that screws into the carb and then into the tee.

    Then a simple 5/16 inverted flare tee. Weatherhead #702x5 / Edelemann #130555 / Everco #702D

    So you know exactly what I'm talking about, adapter fitting.

    I presume you looked in the 426HEMI restoration vendor catalogs under "Fuel System" items? Or possibly in the 440+6 or Corvette 427 3x2 carb fuel line set-ups?

    Not everybody might have those in stock, but they usually were NOT specialty, "one-off application" items.

    Just some thoughts,

    426 Hemi used a regular inverted tee that was 3/8.

    Why do you need it? Replacement? New install?
    Big_John has the best info thus far. Some disassembled pics of the fittings would be helpful, or some details about the set-up. I'm handy with tube fittings (ship engineer is my trade). I know an "old school" carb man nearby who may also be able to help.

    This is a dual quad installation on my '62 300. Factory cast iron intake, using 1406 edelbrock carbs. 5/16 fuel lines and fittings.

    I've looked at your dual Edelbrock photo, and compared it to the "original type install" photo in your first post. Several observations-
    Your current Edelbrock 1406 setup appears to have two adapters already stacked-
    1st adapter- 5/8-20 male (inlet size of carb according to Edelbrock website) to female ???.
    2nd adapter- male ??? to female 5/16 inverted flare.

    I recall that all high performance Mopar fuel systems used 3/8" fuel lines. With this in mind I researched and found-
    5/8-20 male to female 3/8 inverted flare carb inlet fitting. (edelbrock # 8090)
    Edelbrock Square-bore carburetor inverted flare fuel inlet fitting

    An inverted 3/8 flare male x female x female (run ports to branch ports) was found here-
    Brass Brake Tee Fitting, 3/8-24 IFF/IFM

    I believe using these fittings (in lieu of what you show in your dual Edelbrock photo) will allow to closely replicate the OEM set-up.
