Sorry I didn't see this response until now!
The aforementioned shielding of supply, sensor and ground wires is the only thing you can do external to the gauge. Beyond that you can still have interference at the gauge itself, nothing you can do about that as it takes an overall design to be tolerant of electromagnetic interference (component selection, board layout, etc).
