Somewhere along the line I missed the detail of removing the fuel pump. This entry, then, is a belated catch-up. Already got the story on the fuel line in Step 8.
On most modern vehicles, a fuel pump is an electric motor. On the Green Truck, the fuel pump is a mechanical pump driven by the camshaft. Removing it was simple. A couple of bolts, and it was off.
Looking at the fuel pump more closely off of the engine, I have to think that it may have been installed more recently than 1949. Probably a replacement.
