RE: [DML] Low Fuel Light Malfunction

Its possible that the problem is not the low fuel light, but your fuel pickup.  if your fuel pickup line off the pump is not at the bottom of the tank properly you may "run out of gas" before the fuel level actually gets low enough to turn on the light.

Remove your spare tire, and then remove the fiberglass fuel pump access cover.  Clean the area well to prevent contamination. You can then unscrew the retaining ring and lift out the fuel level sender.  When you lift it out of the gas, still plugged in, wait for the gas to drain out and see if the low level light comes on, you can verify that it works. 

Then once its out, look through the opening into the tank with a flashlight (not a lighter) and see if you can see what is going on with the fuel pickup, it has a green or white filter screen, or teabag looking round flat disk on the end of the pickup line. is it flat against the bottom of the tank.

Subject: [DML] Low Fuel Light Malfunction
I had my fuel sending unit replaced with a factory original last year. 
Since the change, my low fuel warning light no longer works. Yesterday 
the fuel tank was very empty. I stopped upgrade at a red light (a very 
steep grade) with the car nose pointing up. The light flickered a bit, 
and then when I accelerated and moved forward, the light came on solid.

However, when the car is on a flat surface the light never comes on 
regardless of how low the fuel is, even when it's bone dry.

The garage that installed the new sending unit refuses to help because 
it's not cost effective over a low fuel light to investigate.

Any opinions of how this can be fixed?
