I took a stab at repairing my OEM fuel sender last night. I have discovered that there are a lot of little things that go wrong inside of these -- mostly from fuel residues causing bad electrical connections. The only problem that I have left is that it took 3 miles worth of driving for the gauge to make it from empty to full (or should we call that 4/4?) Do these floats get less buoyant with age? I don't think it is likely that I have the sliding contacts on the resistive wire too tight. And I'm sure the float isn't jamming mechanically because it moved freely while dry. Any ideas?
