I have a 2005 sportsman 800 and just replaced the fuel pump and fuel pressure regulator. On my old regulator there was a small screen and on my new one there wasn't. So like a bone head I put the little screen on my new regulator now I have no fuel pressure. Just wondering if that little screen could be the problem. Also like a dummy when I was taking the old one out I broke one of the tabs that hold it in and zip tied it so the other two hold. Can a guy just buy the plastic holder for the regulator?
