MPFI fuel pump compatible gas tank

[BATurbo]

I'm in the process of relocating the in-cab fuel tank to a rear mount suburban-style fuel tank in my 70 shortbox. Does anyone know of an in-tank, MPFI capable fuel pump (30-90 psi capable), that will fit into the stock fuel sender location? I'm working towards an LS engine upgrade in the near future, but will probably get the truck running with a carburated small block in the meantime. I'd like to start out using the stock fuel sender and then upgrade to the MPFI pump. Any info is appreciated. TIA!!
