Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Fuel Gauge or Sender Problem?

I agree with Richard, I'd be looking at the sender first. I replaced the sender in my 4/4 last year and was a bit surprised just how crude it was, just some windings around a piece of board with a wiper attached to a float arm. It was obvious how it had failed, the wiper arm seemed to have worn through the windings and it finally broke, leaving a rat's nest of fine wire.



Mind you, even after making sure the new sender was set up and calibrated correctly, I still much prefer to use the trip, refuelling every 250 miles. One thing the repaired fuel gauge has done though is to reassure me that I've still got a decent range above 250 miles should I need it.
