Which Aftermarket gas tank for a 68 Cuda ?

I need to decide on what way to go with my gas tank on my 68 Cuda fastback.
I have the stock tank, but Im leaning to a Hotrod City gas tank , or Rock Valley stainless tank. I'm also considering an in-tank fuel pump for the new tank. I think it would make for a cleaner install.
Any suggestions guys for a tank and fuel pump and lines ........
