My fuel gauge goes from full tank of fuel and stays there for awhile then goes to empty and displaying the low fuel light. Any help would be greatly appreciated, is there any common problems on the blazer, example a bad/loose wire, likely the sending unit, gauges are common to go faulty or any tests I can make to resolve my problem. Does the tank have to be lowered down to acces the sending unit or can you rmove the rear seat and go through the floor to acces the top of the fuel tank. Any help or suggestions would be greatly appreciated Thanks Jody
