Here is what I believe may have happened: The pink wire that goes to the sending unit from the BATT terminal on the tach normally has 12v+ and is also connected to the green wire there at the BATT terminal as well. When your fuel tank sending unit started to fail, that 12v+ on the pink wire starting shorting to ground, through the sending unit, which blew the fuse #3 and caused all the problems on the green wire circuit. If you try and connect a short, fused wire to that pink wire connector going to the sending unit (and make sure the pink wire that goes to the BATT terminal on the tach has been disconnected) and the fuse either immediately blows, or the fuel gauge works for a while and then blows, then you have found your fault and it is in the sending unit.
