While preparing my boat for the upcoming winter I was adding the marine Stabil to the tank. There was a couple of ounces in the upper portion of the Stail and when I opened the cap up to pour it in a small paper disk fell into the tank. The problem is the tank is completely full (40 gallons) and it appears there is not screen on the intake portion of the tank. I called the dealership and they said the only screen for the tank is on the output end of the tank. The paper disk is a little smaller then a dime. Do you think it will cause any problems with the operation of the engine or do I need to siphon all the fuel out and have the tank flushed to retrieve the small paper disk?
