I have a 1994 Mercedes G350, I have been blending a little in it the last few months but am about ready to start doing it full time once I get a couple more things done to the vehicle. My question is about the tank. It has a plastic fuel tank and has been running on diesel. Is there a problem with the blend loosening up some crud in the tank and clogging my fuel lines? My previous vehicle was a Toyota Land Cruiser that I converted to diesel. I pulled the in tank filter and put a large cannister filter after the tank. It seemed to pick up quite a bit of crud but the filter was large enough it never caused any fuel problems. Will a plastic diesel tank have the same potential problems? I guess I could do the same to the Mercedes with the cannister filter but really want to keep this vehicle as stock as possible. Rusty
