9-10) This part really, really sucks. NO other way to put it. You WILL take a bath in gas. BE CAREFUL. Have a friend stand there with a fire extinguisher. Be prepared to use all kinds of inappropriate language. If you don't use that kind of language, you will *think* it...I promise! This was the worst part of the entire install....really! UPDATE: CHANGE THE FILTER WHILE YOU ARE UNDER HERE! Or else you'll be back here sooner than you want. Also, I taped the jaws of some vice-grips and pinched off the feed hose from the gas tank. Spilled a ton less gas than the first time around. This still isn't fun though....
