I got the Bosch 0392022002 yesterday. It is a no go. At least 20% larger w/ larger diameter inlets and outlets.
Also Bosch responded to my technical questions and basically said we don't have an psi or flow numbers, or keep dimensions here. We make the part to fit based on mfr data and you as a customer just buy the replacement. So without seeing and testing each non-Jag pump, there's no way to know which one to buy.

Probably going to either rebuild or bite the bullet and pay $300 plus for a new OEM.
