OK, I'm inside the fuel distributor now!! What IS all this stuff!!

[Cap'n Carageous]

I wanted to show three things in this photo.
#1: Raw gas in the lower chamber of the fuel ditributor
#2: The large o ring around the plunger
#3: The small seal on the plunger bushing (exact center of photo, turned upside down)

Obviously was leaking fuel, so, is the seal on the bushing the culprit? As best I can tell, there is no o ring inside the bushing. The big o ring just seals the fuel distribtor to the housing for vacuum, I think.
