Last weekend, went for a drive in my 2002 RX300. Fuel gauge indicated at least 1/8th of a tank left. Long story short, ran out of gas with the gauge still saying 1/8th of a tank left and low fuel "idiot light" not illuminated. Is this a common problem? Bad fuel gauge sender or something else? Didn't see a fix for this one in the DIY section. Any suggestions welcomed. Please don't say "always fill up when before you get to a 1/4 tank".
