A little update I replaced the clutch switch that combined with with a new sender unit and still no joy, covered a few hundred miles and still no reset.... occasionally the needle will twitch when I turn the ignition on but sits on empty, now and then when I turn the ignition off the gauge will jump to half or 3 /4 full and Stay there and when I turn the ignition back on it drops back to empty, does anyone know the procedure to bench test the gauge once I remove it as I'm not sure of the voltage to try on it as I know it's only using a few volts to trigger it...ive checked the voltage on tune ecu it varies on amount and the low fuel light is doing its job, I'm at a loss as all was fine till I decided I wanted a correct reading so I binned the old sender I was shocked to see how cheap looking that new part is looks like its for a Raleigh wisp
