My fuel gauge works but rite under a quarter of a tank mark
I'm empty and my settings say that I have 28 miles to
empty. I tried to disconnect the batteries, still didn't work.
What else can I do?
Personally I’d leave it alone, your not suppose to run less than a 1/4 tank anyway as it will shorten the fuel pump life. The fuel pump uses the fuel as a coolant, running les then 1/4 tank exposes the fuel pump and then it runs hotter than normal eventually it burns out. But if your really wanting to fix it you will have to drop the fuel tank and replace the entire fuel pump assembly. Not a fun or cheap job.
The fuel empty indicator will light up well before the fuel tank is actual empty, usually with 2 to 3 gallons of fuel left in the tank to keep the pump cool. You never want to run the tank dry. What you are experiencing is normal, just fuel up.
