im planning on changing out my 15 year old factory gm electric fuel pump to a mechanical fuel pump. it is finally taking a crap on me. i have a bbc 454 +.30 over, mild cam, 9.5/1 compression gm hi perf iron large oval port heads with a "stage one" port n polish (according to Santa Ana Speed Shop,, edelbrock performer intake, 750 ( now about a 780)holley DP carb by CJ engineering, and soon adding some lightnings on her. my question is which size mech fuel pump should i be running and which is reliable? then how should i plumb it? i have a fuel filter/water separator sys. that came stock that i want to keep in the loop and i just acquired a aeromotive 40 micron fuel fiter and marine regulator. do i put the 40 micron in front of the fuel pump then to the separator then to the carb?
Thanks
