Question About Husqvarna 322L Carburetor Fuel Lines

[mjlogan2001]

Glad to be a new member of the forum! I have a Husqvarna 322L string trimmer/weed eater that came with the new house we bought. It was missing a carburetor and all the fuel lines. I just got my carburetor in the the mail today. Husqvarna part number 577203204. I've attached a photo of the carburetor. My question is this: There are two fuel ports on the carburetor. A smaller curved port and a larger straight port. Which is the fuel supply port and which is the fuel return port? Thank you!

The straight fitting is the fuel line going into the tank with the fuel filter attached. the curved fitting goes to the short fitting on the primer pump, and then from the long fitting on the primer bulb back into the fuel tank which is the return line.
