If you can't stop it by wrapping with teflon tape as RichG
suggested, then you do need to replace it. Probably someone
tightened it too much, and being plastic, it gave. At least
this is a relatively cheap boat 'repair'. :^) These tanks
tend to run between $15 and $25 depending where you get it
and if it contains a built in fuel guage.

Also, if it's coming up that high and leaking, perhaps the
tank is also being overfilled too. There should be a line
along the side of the tank indicating the maximum fill level.

No on fixing the leak. The answer seems to be to replace the tank.

I was just wondering if this is a common problem with other tanks, too. If
not, I have a much better chance of getting one that doesn't leak.
