missed the point a little. if theres crap in the tank your going to pick it up regardless if its a full tank or empty tank.
Take out the entire dashboard and hook up some volts to the rear of the instrument cluster and see if the fuel light illuminates. Once you know it works stick a hose in the tank and suck out the diesel until the light comes on. Just don't use 12v as the instrument cluster (in the D40 atleast) isn't 12v.
It's good to have all the options even if it's the long tedious and quite possible stupid options.
Options are getting better.
