Fuel gauge & sender resistance issue. HELP

OK back at it. I screwed the insturment cluster to the dash frame. I have a ground from the batter direct to the sender unit. The fuel tank is almost full.When I turn the key on the wait. The needle creeps up just a bit below the "E". At least I have a signal. I took a coat hanger and forced the float down. The guage went upto and past "F". Seen backwards to me. When I let the float up. The gauge returned to the "E" position. I pulled the new sender unit.

It read 5.5 ohms at the all down (Empty) position. It reads 91.4 ohms in the full up (Full) position.

WHAT's THE FIX?

Thanks All
