My 36 year old original mechanical fuel pump started leaking recently, and as I thought it would be a bad idea to have raw gas in the bilge, decided to replace it. By the way, this is a 305K motor from 1981 with a Rochester Quadrajet carburetor. According to the Marine Power owners manual, the part number for the pump is 16.83-00012.
This hasn't been that easy. There doesn't appear to be a modern direct replacement for my Carter pump, and Robert from Chris Craft parts didn't have a solution. I did, however, get a Sierra 18-7365 pump, because it has the same relative location of inlet and outlet ports (clocked)
However, the pump is an AC-style pump. I've checked the pump arm distances from the engine flange, and they are similar, so hopefully I won't break the camshaft or pump. The plumbing will be a little different from the Carter, but I should be able to connect everything.
Just wondering if any of you have replaced a Carter style pump with an AC style pump and had success?
Thanks
