I think an aftermarket electric external pump would be safer and easier to function properly. A return line for the 2.5 would be a good way to prevent vapor lock, something that can happen with some electric fuel pumps (external that is), They make the pumps at different pressures, and volumes, but a regulator would fix both these issues and really save a ton of operation/parts/hunting time to make it work.
