Unless you REALLY need a new one, or its REALLY leaking bad, or you have a REALLY long number at the bottom of your bank printout, just grab some goop and seal her up!
Cept there might be a better way if this is a common problem, I've never had an eeeehime so I wouldn't know specifics - but let's not burn a hole in our pockets just cause of the silly leak! (Plus its a chance to play around with stuff to make it work, who could refuse! - Especially if its already broken, it can only get better!)
[EDIT: Yes as FRAGN'STIEN said, if its not really a 'leak' in the sense of somethign busted, fix it properly
