I am going to start the process of getting my guages working on my project and I really am dreading the fuel sender and guage end of it. I just bought an old Ford van that has guage problems. It would show empty and still have better than a 1/4 tank. I finally put 5 gallons of gas in a can and filled the tank up, then ran it dry after recording the mileage to see. Its the only way I know to get an idea of how far it will go with a full tank. At least I dont freak now when it reads empty with 50 miles more possible. The one advantage to having the guage reading empty with a 1/4 tank left is it doesnt cost as much to fill it!! Just get yours as close to accurate as possible and follow Jim's advice and learn the guages limitations. <img src="/forums/images/graemlins/notooth.gif" alt="" />
