That looks really nice. I met the foundry that Pond uses for this at a show and they use a very good casting process for this. The first photo shows a boss against the direction of "pull" in the casting and is a small core or whatever it's called that has to be manually added after the main cores are put in the sandbox. Not sure what the other two photos show that is in question. I had a nice repro Mike Jackson got for me many years ago, and if I recall, the area around the fuel pump was a little "tricky" as far as maintaining good material thickness everywhere with a long draft that was required on one of the surfaces. This piece looks nice.
