Where is your lift pump mounted, on the side of the engine still ? If it is and you plan to keep it there your best lift pump option is the FASS DDRP , it is designed to be mounted on the engine even though it SHOULD be back as close to the pickup point as possible.

I've only run the Carters on my RAM for 230k miles , they aren't the junk some think they are if you MOVE them back to where they should be , The morons at Chrysler is the reason they are on the engine , not Cummins or Carter.
