My gas gauge dosn't read good will go from full to half to 3/4 back to full when it warms up. Whats the deal? When I switdh to 4x4 low the light won't come up wat's the deal?

 

10 year old truck, what's the deal. Never heard of a gauge doing that. Might try a cheap ebay gauge cluster. Might just be the fuel gauge itself.
