Water in fuel isn't good. Too obvious... next question!

Thanks for the replies, guyz. I know I was vague... but I was just fishing by topic so I could quickly browse the forum for people who'd exp'd similar issues. Have some good ideas about what direction to look in and if I'm not successful... I'll be back. Mahalo!
