The GDI has a low fuel light in the gauge.I only found out by accident, when I was a long way from a filling station and the light came on. I must have driven about 30 miles with that light on and it was uncomfortable. The pump and sender in the GDI is all one, and may have been carried over into other Morgans, because it is a standard low pressure pump.
The sensor float arc is at 2'o clock when full, and 5 o'clock when empty. The fuel intake is very low, as you would expect. The float is behind the pump, which is why you will see a slight increase on the gauge going uphill. I suspect that a full tank puts the fuel level above the float, which is why the float has to first 'float' when the fuel level drops.
