Technical 1948 oldsmobile gas tank fitting

Finally got broken supply fitting out of tank. There is no nut on existing line. What size fitting do I need ? Is there supposed to be a pickup line in tank ? I assume some type of pipe thread fitting with a barb end ?

 

Anybody

 

How about showing a picture of what you have? Maybe then someone could come up with a solution to your problem.

 

I have a 48 olds.. will try to take a look tomarrow.....

 

Looks like a female fitting on the tank. Then a 5/*16 line after that, Hard line to the front,.

 

This is mine

 

So npt fitting with a barb end and a piece of hose should work right

 

Trying to post some pictures . Something went wrong.
Will try when I get to the computer.
Yes there is a tube inside the tank 5/16 size,bends down to bottom of tank at about the middle.
You can do a barbed fitting but where it is located I would be worried something could hurt it
