I've had the same problem in the past. They develop very tiny holes usually
along the seams where the two molded pieces are joined together. Sometimes you
can find the pin hole by squeezing the float to find where the gas comes out.
The only way to drain them is to drill a small hole. Then you have to plug the
new hole and the pin hole, IF you can find it. I tried melting it with the flat
plastic repair tip of a soldering iron. If you are lucky it just might work.
Mine failed so it was a waste of time.
You don't have to replace the whole sender unit. You should be able to find a
spare float somewhere as these floats seem to be used on several different
British cars. I seem to recall that MGBs used the same one.
