A new fuel filter kit with everything you need is $160 from CJ Designs and it is not difficult to install. You only have to remove the left tank and drop the pump assembly out. My 2010 990 has 36000 miles of trouble free fuel filtering. I carry an extra filter kit with me on trips in case I run into bad gas. CJ has also recently developed new billet filler caps with drop in prefilters that are really nice if you know you will be running into bad gas.
