Just because I am paranoid, I elected to replace the engine fuel pump and the rubber line going to it. (With the knuckle out, this seemed like a good time to do it.) I removed the steel line first and it came off about as expected. R&R the pump and hose was only a problem because the upper fastener is a 1/6 of a turn at a time trick...

But, when it came time to put the steel line back in, there was a small disagreement. It was only a small mis-location of the fitting at the pump, but it completely prevented getting both the flare nuts started at the same time. I could have my choice, but no way could I get both. I tried re-bending the line and got it a lot closer, but lying there on my belly board and working around the AC pump was just no fun at all.

Finally I got it close enough to start at both ends, but the nuts would not run home easily. So, I let the carburetor free and ran them in. The carburetor holes were then about 1/4 hole off at the front and 1/2 off at the back.... I snugged up the line nuts and pushed the carburetor over to the holes and screwed it down... Done. I don't like it, but it is together.

Summary, if you have the engine clear enough to see the fuel pump and have any thought of replacing it, do it then. Later is a bear.
