Hi Guys, its probably somewhere on here, but have had no luck searching.
Does anybody know the Specs for original Merc Fuel pump (cool Fuel) for 2001 MAG MPI Horizon (454)
im after GPH mainly and at what pressure. I think they where 46 psi from memory.
Thanks for your help

If no one answers there is a way to find out if that is your system. :thumbs

Hi SB, IT WAS MY SYSTEM! i now run Holley Hp ECU,s and have updated the bulk of everything else, and am having a little bit of Fuel starving problems, and im pretty sure its the new pumps.
So was just after specs on what was there - versus what i have now. Then i can see the differences. Im pretty sure i need lift pumps and surge tanks to fix my issues.
So if anybody knows the original pumps GPH that would be great... Thanks
