When I took the gas cap off this morning the release of vacuum was so bad it startled me and I jumped back. The gas cap has "vacuum only" printed on it. Could it be that I need a "vented" gas cap? Is it possible that because it is not vented that it sucked fuel until there was no air to allow it to keep flowing?
