Title: Newer cast blocks made for motor adaptor plates Post by: Hydros on January 12, 2013, 09:38:01 PM here is a cast block, note there is no way to mount the motor and bearing. This type appears to be a third generation cast block.

This is because of the seal on the pump head. Also note the 9 spline pump shaft.

The two port only needs to be drilled straight down to the ports inside the tank. The three ports require original fittings.
