Am searching for an oem pump and regulator that will supply fuel at 70psi.  Has to have sufficient volume to provide enough fuel for a 300hp 4 cyl, 1390cc 4-stroke top rev limit at 13,800.  I know a business associate that says such a pump and regulator set exists and that Bosch is the manufacturer.  He refuses to tell me the part numbers, and instead wants to sell them to me for a very steep price.  I have not been able to isolate a Bosch catalog or source.  Basically running into dead ends everywhere I turn.  Does anyone know of how I can source this equipment?  Any help will be much appreciated.
