99 Ford Explore Gas gauge light stays on and will not read the gas it will stay on E?

I was wodering if any one could help with this problem? Will it coast a lot to fix? People have been telling me its the floter on the gas tank! Is there a way to find out how to verify that?

You can check if it's the float or the gauge with an ohm meter at the gas gauge wiring connector.

i have a 1993 ford exploreit dose the same thing you would have to replace the hold unit . which right at three hundred dollars .what i did bought a gas gauge like some of stree drag cars have mounted on the dash board and by passed the one that on the truck and it work just as good.
