I just picked up a 1995 U320C with the m11 engine. <br/>The primary fuel filter is listed as a winn hf180. I'm unable to locate this filter while crawling around underneath. <br/>I'm hoping one of you has a diagram or picture showing its location and what it looks like. <br/><br/>Also, they don't appear to be available for purchase online. Is this an obsolete part?<br/>Any help would be...
