Here is the deal. My fuel gauge will not read below 1/4 tank. I know that I am below 1/4 tank cause I ran out of gas, but the needle won't drop below 1/4. So I filled it up and the needle worked fine, until today when it should have dropped below 1/4 it didn't. Now I know this is not a big deal, but I hate when little things like this are broken on my jeep. Any suggestions
