sealing a leaky float

[zahid@serval.sps.mot.com (Zahid Ahsanullah)]

The float on my `80 Spitfire's fuel level sending unit seems
to be drinking petrol. I took it out yesterday to see why
the fuel guage had stopped working and saw that it was full
of petrol. There is a tiny little hole in it which is causing
all the problem. Is there a way to seal it without affecting its
bouyancy. The float is made of flexible plastic and I've already
tried melting the hole shut by soldering iron.
