Can anyone show me the correct Carter and Rochester carburetor inlet fittings and what is used to connect them to the stock filter? On my 1956 Clipper, the filter has 1/8 NPT but I didn’t pay attention to the carburetor side so looking online I see only Rochester carburetors for 1956 Packard which show the fitting in the carburetor having a 5/16 flare. The only photo I can find of my Clipper’s connector is not too clear but it appears that the 1/8 NPT is threaded directly into the carburetor.

Right

1/8 pipe at carb.

And at fuel pump

The picture is correct

Thank you, Riki. The one photo shows a Rochester which appears to have 5/16 or maybe 1/4 flare so how does it connect to the filter?

Yeah the fuel line is 5/16 flare. The elbow is not though. I need to dig through my spares but won't be home until late tomorrow.

There’s no elbow to the filter from the carburetor as far as I can tell. It should just go straight out from the carburetor to the filter, then there is a 90 degree on the filter’s inlet from the pump.

Correct.

What I’m trying to figure out is what the fitting that goes from flare (5/16?) to 1/8 pipe looks like as I am unable to locate such a thing anywhere.

This?

No, not if the carburetor has a female flare as the photo I posted shows. It would need to be male flare on one end and male 1/8 NPT on the other but all I’ve found have inverted male flare.

I am going to be rebuilding my Carter WCFB later this week and I will take pictures of the fuel filter fittings for you. I should have them posted by the weekend if you don't already have the information you need.
