1995 2000SR Gas Venting Issue

[hodgey1943]

It seems from time to time I get gas coming out of the fuel vent on the swim grid. It has happened over the winter when the boat has been winterized and just sitting, it has happened when towing the boat. Is it that the tank is too full? I have a debate going with a buddy about the problem.

most likely it's a combination of full tank..heat expansion and sloshing around ....or if it's sitting...see if you can move the vent line up higher than the tank as much as possible...

Agreed, if it happened over the winter, that is most likely the result of filling it in cooler weather in the fall, then warmer weather in the spring causes expansion of the fuel, which has no way to go but out the vent. when towing the boat is a bit more odd, unless your boat and is not sitting level on the trailer, or the trailer is not sitting level when connected to the tow vehicle. If the trailer isn't level then consider a ball mount with more drop. They should come in one inch increments. It'll also tow better.

I would say in both cases the tank is too full. You should always leave at least 10% of the tank empty for expansion to avoid these types of issues.
