I've got the galloping gas gauge blues and I'm tired of it. I have a custom s.s.16 gallon rectangular gas tank that does not appear to have any type of internal baffle. The gauge is a float on a hinged bent wire arm that jumps every time the car starts to move. Is there anything I can add between the gauge and the tank float that would slow down the gauge response? The hole for the float to go into the tank is about 1 1/2" so I cannot insert anything into the tank without cutting first. Thanks for the advice.
