Here is the replacement pump I got from Holley, the blue one. It was rated at 14 pounds pressure and required the regulator. The earlier (very much new) red one let me down at an IHRA points meet when it would only pump when it was cool. My original one was red, but now 40 years later I'm shocked to find that my Holley rep would have lied to me about the color change thing (sneaky old salesmen anyway). At this late date I can't recall if the red one had the regulator or not. Anyway, this pump is what I used from around 1972 on, on many of my drag race stocker and not so stock racers. The bracket appears to be of the silver variety underneath the layer of "patina".
