If it's brass and you can see the bad area I would use 60/40 (electronic (rosin core)) solder and a small (25-50W) 'soldering copper'.

Hi Daron, Thanks for that, there is a tiny crack running about 1/4" at 90 degrees where the 2 halves of the float join, and it looks like about 1/2" of the original solder in the same area of that join has let go, I have some resin core solder here and a small electric soldering iron, I was just unsure if the contaminants in the old solder will cause me problems.
Regards
Mike
Just clean it, then clean it and just before your solder clean it! If the repair is to big it will get to heavy and not float, then you can try glue, regards Andrew
Set the float in a bowl of ice cubes in the freezer before soldering - will keep the air inside from expanding and open up a pin hole - use flux.
Thankyou everyone, I ended up setting it in the bowl of ice cubes while I soldered, the old crack along the join line of the 2 halves did not want to flow, there was too much contamination in the there, but eventually by using lots of flux and patience the job was done.

Mike

Mike, I'm sure you know to check for leaks/bubbles by immersing in hot water!
