O.k., when I bought the car the guy said that I can only use about half the gas tank because when it gets to half a tank the car reads the tank as empty. The gas gauge reads half a tank and when I fill up I only fill out around 5 or 6 gallons. I haven't tested this out to run over half a tank yet because I'm not sure what the problem is. I took out the sending unit today and didn't really know how to analyze it. It has a mesh bag at the bottom of it that was bent. I just turned the bag around to where it would go deeper into the tank. Apparently it has a high flow fuel pump too but I don't know where exactly I can get to that. Anyways suggestions?
