what frame mounted fuel pump to use

Another option is to use a kit like the Tanks in-tank module:

You can add that to your stock tank. This gives you just one fuel pump to deal with and it is submersed inside the tank in the gas which keeps it cooler and cuts down on noise.

Pretty much what all the OEM uses (In tank) and is proven reliable .
