WTB Six Pack Fuel Inlet Fitting

[Gary AAR]

Looking to buy a fuel inlet fitting for a six pack carburetor.  The photo below shows two styles of the fitting, I am looking for the part on the left.  Several places sell the version shown on the right in the photo, which has the large 1" hex.  Both versions have the 7/8-20 male thread and 1/2-20 female thread with inverted flare for a 5/16" fuel line.  But the part I'm looking for shown on the left has the rounded section and a smaller 11/16 hex. The smaller 11/16" hex makes wrench access easier when trying to install the fitting into the carburetor fuel bowl.

Willing to buy 1, 2, or 3 parts. 
Let me know what you have.
Thanks.
Gary.

What Holley part number did you start with?  Would your friend be willing to modify more parts?
Thanks.

I have to find them so I can take a picture. I put them away until the next time I have to work on the carbs. I know he didn't turn them completely round. Not sure why. I mainly just wanted them hex so I could hold them while removing the fuel lines, but he did the other also. The part number was HO26-27 that they modified. I'm not sure if he would do another set. He complained about doing these 3....Joe

Gary, does it have to be 5\16?
Here is the 3/8 version

Thanks, but yes it does need to be for a 5/16 fuel line.  5/16 is the original stock size for a 340 6-pak engine.
