To build a better pump, it would have to be significantly different enough not to infringe on the OEM patent. Otherwise, it would be asking for legal troubles... A new pump would be a risky venture for a limited and shrinking market to begin with. Been there done that with our Torque Converters. That was known going in, but had the demand to make better designs worth it.

My perspective will always be from an entrepreneur's when the topic is about making a product. It will always be different than a regular members on most topics. Regular members can post care free, while sponsors can't always. One example: Some sponsors can't risk their entire livelihood's and businesses by posting or providing copyrighted or privileged material, information or specifications some members and some potential customers will ask for.
