HZJ79.... fuel gauges are all over the place. Main is full but gauge moves between full, half then back to full. Sub says just above empty but it's at least half. I have removed the sub sender and it reads full when it's out of the tank...... Are the two gauges on the same circuit? Is there a low fuel warning light on the sub tank? I have 3 wires to the sub sender but only 2 coming out..
