Would that be a Clock and Fuel Gage? Several sites sell these OEM add-ons, all at the same prices. I've not seen a "good" deal on them. The intank sending unit, by all reports, are poorly factory set to signal low fuel at or about the half tank level; which is fortunate for those with a 130 mile monkey butt limiter. I've read herein that this sending unit sends the same erroneous signal to the bar mount gage. Crap in = crap out. There is discussion herein about how to get into and adjust the mechanism. I have such poor luck with the forum seach engine. Otherwise I'd point in that direction.
Paul, I am sure you can bend something in the fuel tank, but I took mine back and it was adjusted under warranty. Now comes on with a gallon and a half left. But I am still going to the fuel gauge. It will say empty at about the same. But when I wake up after being overserved on a long trip I don't have to wait till the light comes on to know about where I am on gas.
Mine goes off at about the same as yours but if you want to customize it a little. Some people like to ride on the edge. For me it's a good excuse to get my old butt off the seat with out saying uncle.
