Forgive the obvious question, but are the wires underneath the tank plugged in? I don't know if it matters what order they are on, but there are two little push-on wires that handle the level. Also, you should see that light start to come on at about 110 miles, if you are getting nervous about the level. Then supposedly you have another 30 miles or so to go, but I've never had it past about 120. I don't relish the thought of pushing this thing to a gas station.
Insert clever phrase here that will garner respect and love.
