Looking to see if CMI E-top headers can handle discharging water from an Eickert 2-stage water pump. Custom Marine says they can handle that much volume with little back pressure. 2-stage pump feeds engine on front stage and coolers on the inner stage.

Run the engine hose to the bottom of the header and the chiller hose to the top of the header. I don't think there should be any issues.

Bingo....

i have to run it the opposite. The stage supplying the coolers also is the by pass for the headers. Either way i think the CMI's can handle a lot of water which won't put to much back pressure on the engine water for for cooling.
