I don't really know for sure. I have heard
of it happening, but it's never happened to me, and I can't think of anyone who has specifically mentioned it to me.
My old CSV had a wobbly plastic part (the fuel fitting and electrical connector), so I pulled it and replaced it. I don't think it was leaking around the pintle, but I don't really know.
