I this case it appears the electric is before the mech pump ? I dont think the electric can pump thru the mech pump with internal check valves ? As Doug said the mech pumps depending on what you have installed will give you what you need in GPM by far more then you will ever need ... both electric and mech have pro's and con's I prefer mech pump for safety reasons ... unless of course you are running some sort of exotic fuel induction system like webers or EFI ... My 2 cents.
