I was looking at a holley black. Looks like it will do the job well. Just find something a high flowrate and around 14psi or so. I prefer the mechanical for simplicity though.

It can run up to about 20psi though. My piston pump runs 18psi at idle.

I may step up to the holley black and convert to all -6AN lines because my fuel pressure reads real low when it's cold. I need to figure out if it's the gauge because sometimes it's fine.

I was gonna run the electric in parallel with the piston pump (cummins p/n 3936320) and maybe use a pressure switch to turn the electric on if pressure drops below a certain point.
