Sloshing gas tank
Thanks John and Smillie, I have considered somekind of shock, but dont know it could be installed through the small pick-up tubing hole. I am again looking at the original fuel level sensor, through the small slot where the float arm pivots, not too clear but there appears to be a larger wear area on the resistance wire that corresponds with the float angle of 3/8 full tank. I am convinced that this the problem since the new sensor cured the problem for about 5 years. Maybe I need more oil in the gas tank to reduce the wear factor. Years ago fuel tank builders were adding baffles and stilling-wells to cure this problem of sloshing fuel. Right now my cure is to fill my tank when the level is half full. At least, I will save money since the gas price would be higher if I waited until the tank was closer to empty, Ha! Ha!.
