I drained and flushed my 4/4 fuel tank yesterday to get rid of as much "bits" in the fuel - I have had a couple of incidents with power loss. I put the clean and filtered petrol back in and the fuel gauge hardly moved from empty - there was 3.25 gallons in there. Before flushing the gauge was reading a bit higher. For some reason it is now reading a fair bit lower. I have taken the sender out and the float seems free inside the tube. I cleaned and re-made the wire connections but no change
I have done about 50 miles since and the gauge has dropped very slightly. I estimate just about 2 gals left inside now.
I am doing a long run tomorrow - 200 or so miles so will fill up first and see what the gauge shows.
I read about adjusting the gauge/sender on Gomog so will see what happens with a full tank
Full = 55 litres from spec and calculation from tank dimensios so we will see what happens. Until its sorted I am driving on the odometer!
Anyone had similar-ish problems?
