So, just a quick update on my situation.

I managed to change out the fuel sender OK with the FG unit. While the FG unit is a slightly different in the orientation / angle of the float to look at, the dimensions from mounting point to float centers at low and high were about the same, so I went with that.

I completely cleaned out the tank, wiped it out, even vacuumed up the crap in the bottom (my last float wire was rusty and dropped scale when removing).

Put it all back together, added fuel and the gauge is still not working. I checked the unit that I removed and resistance varied from about 40ohms to 240 for full to empty, therefore the sender was probably OK.

So I guess that means that I have a faulty fuel gauge? Have others had trouble with that and how do you go about a fix?
