i'M Getting ready to dyno a 509 thats going to make around 580 to 600 hp. It has a VERY specific inline 45 gph carter fuel pump built into bracket for fuel filter (Carter pump, OMC motor). I can tell with 99% certainty its NOT going to keep up. YES, I can buy a better low pressure GENERIC (HOLLEY ETC) pump and regulator, BUT im looking for a low pressure INLINE pump that will specifically boolt to this retarded omc brackets/filter head
