C1 57 fuel gage

[Verle R.]

The fuel gage has started fluctuating wildly when the tank is something less than full. I know it did not do this before.

I assume the damping is in/on the back of the gage, what should I look for.

Thank you,

First check the sending unit in the tank and the connections. Also, it wouldn't hurt to add a dedicated ground to the sending unit flange.

The rheostat inside the sender can get shellac build up on the wires, which in turn you loss a ground connection, but can be opened and cleaned if your problem is not a ground wire or bad gage.

Re: C1 57 fuel gage

I installed a new tank and new sending unit last spring. It has worked properly until recently.

I will check the ground from the sending unit.

The fluctuation is directly related to the sloshing of gas in the tank. If I turn the switch on after the car has been setting still for a while the gage is steady.
