Re: Fuel Pump

Is there an "AC" casting on the top and bottom of the pump? Is the pump stamped "4657" with or without 2 additional letters on the flange? Is there a 2-digit casting (example: "64") in the hole near the outlet with anywhere from 1 to 12 radial line segments (like a clock)? Exactly where is the "230" stamping on the pump?
