A fluid overfill probe is resistant to failure caused by physical stresses resulting from thermal expansion of probe components. A fluid level detector is connected to circuit components that are mounted on a circuit board located in a housing of the probe. The circuit board is located within a tube that is positioned within, and secured to the housing, and the circuit board is secured to an inner surface of the tube along its edges. The tube has a shape and rigidity sufficient to maintain a gap between the circuit components and the inner surface of the tube such that thermal expansion of probe components result in no physical stress to the circuit components.
