I think the Bosch inline pumps that Endyn carries are rated to at least 120psi, and I'm not really sure what my old pump was rated at. Airtex pumps are rated to about 125psi, I think. Most people either use a Bosch, the Airtex that comes with the DRAG kits, or an MSD pump. I think the MSD is like $76 from Summit Racing.
