I personally had to replace main fuel shutoff valves in engine feed systems (back in the 1980s) because intuition and inverse square laws did not prevent them from closing in an unscheduled manner then. The valves were redesigned and the wiring was provided with an improved electrical connector. And guess what, EMI filter modules were added between the connector and fuel shutoff valve.
Means nothing unless you know that the fault was caused by *radiated* EMI rather than conducted.
