I've researched all the appropriate threads and I believe I should install a SL55(AMG?) fuel pump (to provide increased fuel volume) needed with my 62mm Karmen supercharger pulley install. (note I am keeping the stock crank pulley so running non-stacked). I just would like to throw this out here to get some verification that the SL55(AMG?) fuel pump is the currently recommended fuel pump mod. Is the OEM SL55(AMG?) made by Pierburg or Bosch? Also I'd like to confirm that will be a direct bolt in installation, right? What's the latest and greatest advice??
