Message	If the Orings you've got have swelled, then they are the wrong type. The factory O-rings (Nitrile), Viton, or HNBR rings will not swell in contact with fuel. Other materials probably will though. If you used hardware store o-rings, that is your issue and you need to correct before you have some serious engine damage.
