This is a great site with many people that could help you. I'm sure someone there will have had similar experiences. I have a two tank kit on my car and right now i'm having filter clogging problems because cold fitering five gallons overnight completely clogs up the bag with whatever that slimy stuff is. Tonight I'm going to try to clean it out with gasoline because I heard that should do the trick. I also mix one gallon of gas for every five gallons of veggie and that seems to help the problem somewhat. The people on this website should be of some help. I know they've helped me many a time.
