[DeTomaso] Electric Water Pumps, The 21st Century of Water Circulation

[Julian Kift]

Actually the Meziere pumps are sold without fittings, you just purchase whatever size you need, either hose ends or AN fittings.
I run an electric only water pump on the Ultima and it gets used hard in SCCA events, never had an issue with the pump or cooling. Similarly I've installed a Meziere on the GT40 to give me a flat firewall. For that application (SBF 302) I actually removed the impeller and shaft out of a mechanical aluminum pump and welded it up to create an empty plenum, this way water hose routing was unaffected.
I seem to recall the Meziere was not a free flow through pump, whereas Stewart was and that influenced people's choice where they are using it an electric booster pump, maybe that has changed or my memory is fading...
Other advantages are you can control pump speed to engine temp, set your pump and fans can be set to run on after engine shutdown. All easily doable with a PWM controller like the PowerOne Dave Londry sells http://www.emspace.com/
