AudiSpaulding

well, I just went out to do some stuff on my car, and i noticed what appears to be some gas soaking through the cork gasket on the fuel distributor. Its only a very mild leak, after letting it run for a while, a very small drip will form. Car runs near perfect (slight idle pulse periodically)and I'm getting about 20mpg out of it.

Whatever is soaking through the gasket dries and gets sticky after sitting for a while...

Any idea what would cause this? it never did it before i changed my fuel filter. and do you think it is something i should worry about?
