<VV> Fuel tank sender leaking?

[Les]

A friend's '63 is dripping some fuel. Looks like it's coming from around 
the fuel line where it enters the tank - where the pipe goes into the 
sending unit. The pipe is a little loose in the sender - is it supposed 
to be tight? Any easy repair for this? I'm wondering if I can use some 
fuel tank sealing epoxy (easiest), remove the sender and solder the pipe 
(cheapest but some work), or replace the sender ($ and not necessarily 
available...).

Thanks,
Les
