I have been running the Meziere standard pump for a few years in a stock housing.
Electric Pump Mopar, insert style
I did it so I could run a bigger CFM electric fan. I think it gave me 3/4" extra clearance vs the stock style pump with a pulley bolted to it. I would be interested in the size of the CVR Pump if someone has one. Gasket surface to end of the unit.
