The plunger is stuck but I'm sure with a little heat and some patience it should free up. The plunger driver link is still on the plunger. I believe this pump is used on many sizes of the Fairbanks Morse Y engines.
The pictures tell the story. These fuel pumps are extremely hard to find in the wild or even in the collector network so if you need one here is your chance. It will likely be a long time before another one comes along!
