78 GMC Sierra Grande Fuel Tank Selector Valve

I have got a 1978 GMC Sierra Grande pickup truck with the fuel tank selector valve out. Is there any way I can tear in to it and fix it or do I have to buy a brand new one? I am wanting to restore this truck. It means a lot to me. Thanks for any help

I got mine at the dealer, but that was a few years ago, even at the dealer it was under $50.

Thanks for the help. I was also wondering. Will fuel eat up jb weld or would it be fine for a temporary fix?

My fuel filler necks on both tanks are cracked and leak fuel. The truck was sitting in a field for 10 years because the transmission was out.
