Well run out of fuel twice in the one day the other day,so its time to fix.Fuel gauge only reads 1/2 tank when full,so today i pulled te sender. Float looked fine ,no holes or fuel inside,resistance on the sender coil was about 10 ohms empty & about 75 full.Resister coil looked fine,circut from point A to point B so i cleaned everything up & put it back together,no change. The gauge seems to be ok,when you ground the wire out gauge reads full & returns to empty. Anybody got any ideas whats up . Thanks Ron.
