Can this be welded?

This is the flange that mounts the fuel pump on my Avatar '32.. At some point someone over tightened the nut and cracked the flange on one side. The crack does not go all the way through but it has rendered the bottom of the flange a little cupped. Some JB weld was slopped on to help secure it. Now it's time to have the fuel pump rebuilt as it's leaking. As long as it's apart looking to clean this up and make it right. I know nothing about welding what appears to be cast aluminum, or if it's even possible. If there's someone recommended near me in Wa State to rebuild this I'm open to suggestions.
Thanks, Tom
