There is a fuel lift pump on the Ford Ranger with the 4d55t. It is located almost right underneath the ip and is bolted to the inside of the drivers side frame. It's a cylindrical pump wrapped in insulation.

Both pumps are rated the same for gph and pressure.

I need to change my lift pump and for the same price as the original pump can get a lift pump that is rated for 6 to 4.5 psi and 34 gph. If I make the switch to a more powerful lift pump will I need to make other adjustments to the vehicle, adjust the ip? Is this a good modification to increase performance and power? What tunings need to be done to accommodate for the extra lift?
