2004 Sportster 4-TEC Gas tank vent leaking gas

[wlester]

It was leaking when we first bought the boat (used), but was told by the dealer that it is the pressure from the change in heat during the summer. OK. I can live with that. However, it started leaking in our garage yesterday (March 9, 2014 in Minnesota). It started getting warmer, but it was still in the 30's range.

I read a post on here from a different user where someone said that he probably overfilled his tank. I filled it after winterizing and had it in our garage all winter with no leaks.

Does anyone know why it is leaking now?

I had the same basic problem.

Maybe your gas has expanded due to heating up and flowed out the vent. Its a really poor design. Before this season starts I'm going to put some sort of check valve in it.
