1952-59 Ford Gas tank fitting

I need to find a new fuel line fitting for my -52,the one that goes into the tank.
What is the thread size.?

 

I believe it's a 3/8 inverted flare.

 

It may be 3/8 pipe to 5/16 inverted flare. Parts store should have one.

 

When it comes to br*** fittings many parts stores **** at it, I found everything for my brake lines and fuel lines at Ace Hardware if you have the old one they will match it up.
