Hi,
After sitting a while (3-4 days or longer), the gasket on the fuel filter "can" leaks quite badly. Then after sitting a while, it doesn't leak any more. So, the gasket appears to swell when wet and seems to shrink when dry. I use 10% ethanol premium pump gas and was wondering if that could be the issue. If it is, I'd like to install an electric fuel pump somewhere along the fuel line. Has anyone ever done this? It's been going on for a long time and I'm getting kind of tired of it.
