had same problem, but thankfully it is sorted. 1 time it would show full and the next it would show empty even after I fill up. What I found after stripping a few things off was that the terminals under the tank for the sender unit were a bit green and the rubber cover was twisted. Dismantled the tank, cleaned the terminals, untwisted the rubber cover, put a piece of sponge on the frame where the fuel pump is as when the tank is lowered the terminals maybe touching and earthing against the crossbar under the tank. Did all this and since then had accurate readings on my gauge. 
It's not a speed limit it's a target
