I've been a bit disturbed by the number of people advocating using electricity in contact with the fuel... I have a lot of circuit diagrams for modern vehicles, and often advise people re installing equpment or modifying these modern vehicles. It's part of my job. :o) I see NO modern vehicles using electricity in direct contact with the fuel!!!! The 3 main types of fuel level sensing in modern vehicles are: * Simple pressure gauge (senses liquid height above the pressure sensor) * Sliding float over sealed tube with reed switch. * Thermistor sensor (senses difference in heatsinking between fuel and air) ALL of these 3 types have one thing in common, there is NO direct contact between fuel and electricity. Call me a safety freak if you must, but I would NEVER consider using live electricals in contact with fuel. If the fuel container is punctured, and some atmospheric condition causes the fuel to atomise, you have real danger situation presented. Surely if the cost/hassle of contruction is similar, you MUST prefer a system with no direct electics in the fuel?? Please argue if you think i'm wrong, or argue with all the modern vehicle manufacturers if you like... -Roman -- http://www.piclist.com#nomail Going offline?
